26 Formatting Issues # of decimal places arbitrary some decimals are displayed, others are not numbers are not aligned

27 Formatting Output recall that cout has the following syntax: cout can actually take a formatting manipulator as well: these manipulators control what the output will look like cout << expression cout << expression or manipulator

28 Fixed and Scientific by default, C++ has a limit on the number of digits it uses when displaying a floating-point number significant digits on my computer, this default is 6 (common) what happens when the number has more than 6 digits? #include using namespace std; int main() { cout << 123456.7 << endl; cout << 1234567.8 << endl; return 0; }

29 Only 6 digits are shown Number is rounded off

30 Fixed and Scientific we can instruct C++ to display all of its digits (as many as it can store) by setting either the fixed flag or the scientific flag if fixed is used, display numbers in fixed format if scientific is used, display numbers in scientific notation Syntax: cout <<fixed; // fixed format cout <<scientific; // sci. format

31 Example: #include using namespace std; int main() { cout << 123456.7 << endl; cout << fixed; cout << 123456.7 << endl; cout << scientific; cout << 123456.7 << endl; return 0; }

32 Fixed and Scientific the statement cout << fixed has the effect of turning on fixed mode all floating-point numbers from that point forward will be displayed in fixed mode until: 1) fixed mode is turned off 2) scientific mode is turned on the same applies to scientific mode

33 Example: #include using namespace std; int main() { cout << fixed; cout << 123456.7 << endl; cout << 100.0 << endl; cout << scientific; cout << 123456.7 << endl; cout << 100.0 << endl; return 0; }

34 Fixed and Scientific by default, both fixed and scientific are off we will refer to this as default mode to turn off fixed (2 ways) cout << resetiosflags(ios::fixed); cout.unsetf(ios::fixed); // textbook way to turn off scientific: cout << resetiosflags(ios::scientific); cout.unsetf(ios::scientific); // textbook way

35 Example: #include using namespace std; int main() { cout << fixed; cout << 123456.7 << endl; cout << 100.0 << endl; cout << resetiosflags(ios::fixed); cout << 123456.7 << endl; cout << 100.0 << endl; return 0; }

36 setprecision by default, C++ has a limit on the number of digits it uses when displaying a floating-point number significant digits on my computer, this default is 6 (common) can this number be set higher, without resorting to fixed or scientific mode? use the setprecision flag Syntax: cout << setprecision( ); # of digits

37 Example: #include using namespace std; int main() { cout << 123456.7 << endl; cout << setprecision(7); cout << 123456.7 << endl; return 0; }

38 setprecision in default mode, setprecision sets the number of digits for displaying what does it do in fixed and scientific mode? sets the number of decimal places

39 Example: #include using namespace std; int main() { cout << setprecision(3); cout << 123.45 << endl; cout << fixed; cout << 123.45 << endl; cout << scientific; cout << 123.45 << endl; return 0; }

40 setprecision note that setprecision does not change the value being stored in memory it simply affects the displayed value

41 Example: #include using namespace std; int main() { double x = 141.5; cout << setprecision(4); cout << x << endl; cout << setprecision(3); cout << x << endl; cout << setprecision(4); cout << x << endl; return 0; }

42 showpoint by default, the number 123.0 is shown as 123 in default mode for some compilers, this is also the case in fixed mode use the showpoint flag to force floating point numbers to show their decimal place

43 Example: #include using namespace std; int main() { cout << 123.0 << endl; cout << showpoint; cout << 123.0 << endl; return 0; }

44 Back to our example: suppose I want all of my numbers to be displayed with exactly two decimal places use the following formatting flags: fixed showpoint setprecision(2)

45 Write a program that takes in a salary for the month, calculates the deductions, and produces a paystub for the employee // continued cout << "------------------------------------------------------------" << endl; cout << "Earnings Deductions" << endl; cout << "------------------------------------------------------------" << endl; cout << "Description Amount Description Employee Employer" << endl; cout << "------------------------------------------------------------" << endl; cout << "Salary " << salary << " Tax " << tax << endl; cout << " CPP " << cpp << " " << cpp << endl; cout << " EI " << ei << " " << ei << endl; cout << " Pension " << pension << " " << pension << endl; cout << " Health Plan " << 35.00 << " " << 85.00 << endl; cout << "------------------------------------------------------------" << endl; cout << "Total " << salary << " Total " << your_d << " " << their_d << endl; cout << "------------------------------------------------------------" << endl; cout << " Net Pay " << salary – your_d << endl; return 0; } Add formatting flags!

56 Our spacing worked when: salary was a four digit number EI was a three digit number It would be nice if: everything in each column was printed at the same width, regardless of how many characters the actual value has

57 setw stands for set width sets the number of characters that will be used to display the next expression syntax: cout << setw( ); # of chars

58 Example: #include using namespace std; int main() { cout << "|" << "Kev" << "|" << endl; cout << "|" << setw(5) << "Kev" << "|" << endl; return 0; }

59 Kev| What happened? cout << "|" << setw(5) << "Kev" << "|" << endl; ||

60 Kev| What happened? cout << "|" << setw(5) << "Kev" << "|" << endl; ||

61 Kev| What happened? cout << "|" << setw(5) << "Kev" << "|" << endl; || This tells C++ to use 5 characters to output the next expression.

62 Kev| What happened? cout << "|" << setw(5) << "Kev" << "|" << endl; || This expression requires only three characters for output.

63 Kev| What happened? cout << "|" << setw(5) << "Kev" << "|" << endl; || This expression requires only three characters for output. when the field width is bigger than the expression, C++ "pads" the expression with spaces the padding is placed on the left hand side expression is padded with two spaces before output the expression now has 5 characters

64 Kev| What happened? cout << "|" << setw(5) << "Kev" << "|" << endl; ||

65 setw what happens if the output requires more characters than setw gives it? cout << setw(5) << "Computer Science" << endl; the field width is always set at least as big as the output

66 Note unlike setprecision, fixed, scientific, and showpoint, setw only applies to the next expression (not all expressions hereafter) cout << setw(5) << "Kev" << "Kev" << endl; displayed with 5 characters (2 pad spaces) displayed with 3 characters (no padding)

67 Back to our previous example: we can break up the table into 6 columns each column has a specific width ------------------------------------------------------------- Earnings Deductions ------------------------------------------------------------- Description Amount Description Employee Employer ------------------------------------------------------------- Salary 3000.00 Tax 600.00 CPP 150.00 150.00 EI 60.00 60.00 Pension 240.00 240.00 Health Plan 35.00 85.00 ------------------------------------------------------------- Total 3000.00 Total 1085.00 535.00 ------------------------------------------------------------- Net Pay 1915.00 8 14 5 10

68 When outputting our data, we will include a setw for each expression, depending on which column it is in for the first column: cout << setw(14) << "Salary" for the second column: cout << setw(8) << salary; etc What do we do with a blank field entry? cout << setw(5) << ""; // output 5 blank spaces

69 Write a program that takes in a salary for the month, calculates the deductions, and produces a paystub for the employee cout << "-------------------------------------------------------------" << endl; cout << setw(14) << "Earnings" << setw(8) << "" << setw(5) << "" << setw(14) << "Deductions" << endl; cout << "-------------------------------------------------------------" << endl; cout << setw(14) << "Description" << setw(8) << "Amount" << setw(5) << "" << setw(14) << "Description" << setw(10) << "Employee" << setw(10) << "Employer" << endl; cout << "-------------------------------------------------------------" << endl; cout << setw(14) << "Salary" << setw(8) << salary << setw(5) << "" << setw(14) << "Tax" << setw(10) << tax << endl; cout << setw(14) << "" << setw(8) << "" << setw(5) << "" << setw(14) << "CPP" << setw(10) << cpp << setw(10) << cpp << endl; cout << setw(14) << "" << setw(8) << "" << setw(5) << "" << setw(14) << "EI" << setw(10) << ei << setw(10) << ei << endl; cout << setw(14) << "" << setw(8) << "" << setw(5) << "" << setw(14) << "Pension" << setw(10) << pension << setw(10) << pension << endl; cout << setw(14) << "" << setw(8) << "" << setw(5) << "" << setw(14) << "Health Plan" << setw(10) << 35.00 << setw(10) << 85.00 << endl; cout << "-------------------------------------------------------------" << endl; cout << setw(14) << "Total" << setw(8) << salary << setw(5) << "" << setw(14) << "Total" << setw(10) << your_d << setw(10) << their_d << endl; cout << "-------------------------------------------------------------" << endl; cout << setw(14) << "" << setw(8) << "" << setw(5) << "" << setw(14) << "" << setw(10) << "Net Pay" << setw(10) << salary - your_d << endl; return 0; }

71 Note: we can concatenate consecutive blanks into one long blank instead of: cout << setw(14) << "" << setw(8) << ""; we could write: cout << setw(22) << "";

72 Write a program that takes in a salary for the month, calculates the deductions, and produces a paystub for the employee cout << "-------------------------------------------------------------" << endl; cout << setw(14) << "Earnings" << setw(8) << "" << setw(5) << "" << setw(14) << "Deductions" << endl; cout << "-------------------------------------------------------------" << endl; cout << setw(14) << "Description" << setw(8) << "Amount" << setw(5) << "" << setw(14) << "Description" << setw(10) << "Employee" << setw(10) << "Employer" << endl; cout << "-------------------------------------------------------------" << endl; cout << setw(14) << "Salary" << setw(8) << salary << setw(5) << "" << setw(14) << "Tax" << setw(10) << tax << endl; cout << setw(14) << "" << setw(8) << "" << setw(5) << "" << setw(14) << "CPP" << setw(10) << cpp << setw(10) << cpp << endl; cout << setw(14) << "" << setw(8) << "" << setw(5) << "" << setw(14) << "EI" << setw(10) << ei << setw(10) << ei << endl; cout << setw(14) << "" << setw(8) << "" << setw(5) << "" << setw(14) << "Pension" << setw(10) << pension << setw(10) << pension << endl; cout << setw(14) << "" << setw(8) << "" << setw(5) << "" << setw(14) << "Health Plan" << setw(10) << 35.00 << setw(10) << 85.00 << endl; cout << "-------------------------------------------------------------" << endl; cout << setw(14) << "Total" << setw(8) << salary << setw(5) << "" << setw(14) << "Total" << setw(10) << your_d << setw(10) << their_d << endl; cout << "-------------------------------------------------------------" << endl; cout << setw(14) << "" << setw(8) << "" << setw(5) << "" << setw(14) << "" << setw(10) << "Net Pay" << setw(10) << salary - your_d << endl; return 0; }

73 Write a program that takes in a salary for the month, calculates the deductions, and produces a paystub for the employee cout << "-------------------------------------------------------------" << endl; cout << setw(14) << "Earnings" << setw(13) << "" << setw(14) << "Deductions" << endl; cout << "-------------------------------------------------------------" << endl; cout << setw(14) << "Description" << setw(8) << "Amount" << setw(5) << "" << setw(14) << "Description" << setw(10) << "Employee" << setw(10) << "Employer" << endl; cout << "-------------------------------------------------------------" << endl; cout << setw(14) << "Salary" << setw(8) << salary << setw(5) << "" << setw(14) << "Tax" << setw(10) << tax << endl; cout << setw(27) << "" << setw(14) << "CPP" << setw(10) << cpp << setw(10) << cpp << endl; cout << setw(27) << "" << setw(14) << "EI" << setw(10) << ei << setw(10) << ei << endl; cout << setw(27) << "" << setw(14) << "Pension" << setw(10) << pension << setw(10) << pension << endl; cout << setw(27) << "" << setw(14) << "Health Plan" << setw(10) << 35.00 << setw(10) << 85.00 << endl; cout << "-------------------------------------------------------------" << endl; cout << setw(14) << "Total" << setw(8) << salary << setw(5) << "" << setw(14) << "Total" << setw(10) << your_d << setw(10) << their_d << endl; cout << "-------------------------------------------------------------" << endl; cout << setw(41) << "" << setw(10) << "Net Pay" << setw(10) << salary - your_d << endl; return 0; }

74 We still have a problem: setw automatically pads on the left now, our descriptions are right aligned

75 left and right when left is used, padding spaces are put on the right (the field is left-aligned) when right is used, padding spaces are put on the left (the field is right aligned) note that left and right are not one-time use when left is used, everything is left-aligned until otherwise specified (same for right)

76 Back to our previous example: column 1 and 4 are left aligned column 2, 5, and 6 are right aligned ------------------------------------------------------------- Earnings Deductions ------------------------------------------------------------- Description Amount Description Employee Employer ------------------------------------------------------------- Salary 3000.00 Tax 600.00 CPP 150.00 150.00 EI 60.00 60.00 Pension 240.00 240.00 Health Plan 35.00 85.00 ------------------------------------------------------------- Total 3000.00 Total 1085.00 535.00 ------------------------------------------------------------- Net Pay 1915.00

77 Write a program that takes in a salary for the month, calculates the deductions, and produces a paystub for the employee cout << "-------------------------------------------------------------" << endl; cout << left << setw(14) << "Earnings" << setw(13) << "" << setw(14) << "Deductions" << endl; cout << "-------------------------------------------------------------" << endl; cout << setw(14) << "Description" << right << setw(8) << "Amount" << setw(5) << "" << left << setw(14) << "Description" << right << setw(10) << "Employee" << setw(10) << "Employer" << endl; cout << "-------------------------------------------------------------" << endl; cout << left << setw(14) << "Salary" << right << setw(8) << salary << setw(5) << "" << left << setw(14) << "Tax" << right << setw(10) << tax << endl; cout << left << setw(27) << "" << setw(14) << "CPP" << right << setw(10) << cpp << setw(10) << cpp << endl; cout << left << setw(27) << "" << setw(14) << "EI" << right << setw(10) << ei << setw(10) << ei << endl; cout << left << setw(27) << "" << setw(14) << "Pension" << right << setw(10) << pension << setw(10) << pension << endl; cout << left << setw(27) << "" << setw(14) << "Health Plan" << right << setw(10) << 35.00 << setw(10) << 85.00 << endl; cout << "-------------------------------------------------------------" << endl; cout << left << setw(14) << "Total" << right << setw(8) << salary << setw(5) << "" << left << setw(14) << "Total" << right << setw(10) << your_d << setw(10) << their_d << endl; cout << "-------------------------------------------------------------" << endl; cout << setw(41) << "" << setw(10) << "Net Pay" << setw(10) << salary - your_d << endl; return 0; }
