Place: Math & General Classroom 2.206
Closed-book exam
You can take a piece of cheating paper with A4 size
Write down whatever that you think is important (on both sides) with any font size

4. Chapter 2: Basic Elements of C++
Special symbols, keywords, rules of identifiers
Basic data types
int, float, double, char, string
Operators
Arithmetic operators and their precedence
+, -, *, /, %, +=, -=, *=, /=
Increment/decrement operator
++, --
Declaration of variables
int first=13, second=10;
char ch=' ';
Input/Output statement

5. Chapter 3: Input/Output
Declaration of input/output stream
Usage of cin and cout (as well as other istream/ostream variables)

6. Chapter 4: Control Structures I (Selection)
Relational operators and precedence
Comparison operators
<, <=, >, >=, ==, !=
String comparison
Logical operators
&&, | |
Evaluation of logical expression

7. Chapter 4: Control Structures I (Selection, cont'd)
Syntax and usage of the selection structure
One-way selection: if () { }
Compound statements
Two-way selection: if () { } else { }

8. Chapter 5: Control Structures II (Repetition)
Repetition structure
Syntax and usage of the "for" loop
The nested for loop

9. Chapters 6 & 7: User-Defined Functions
Two types of user-defined functions
Value-returning functions and void functions
Differences
Syntax of function heading
Function prototype
Function heading without the body of the function

10. Chapters 6 & 7: User-Defined Functions (cont'd)
Function call
Use function name together with the actual parameter list
Two types of formal parameters
Value parameters
Reference parameters
Differences
Scope of an identifier
Local identifier
Global identifier

11. Chapters 6 & 7: User-Defined Functions (cont'd)
Function overloading
several functions with the same name but different parameter lists
Default parameters in function prototype
Places of default values
Default values cannot be assigned to reference parameters
See legal and illegal examples in lecture slides

12. Chapter 8: User-Defined Simple Data Types, Namespaces, and the string Type
Syntax of declaring an enumeration data type
Syntax of declaring a namespace
String data type
Syntax of declaring and initializing a string variable
string name = "William Jacob";
Syntax of accessing characters in the string using array subscript operator []
name[0]

13. Chapter 8: User-Defined Simple Data Types, Namespaces, and the string Type (cont'd)
Basic operations/methods of string data type
str = name + " Day";
name.length()

14. Chapter 9: Arrays and Strings*
Declaration and initialization of arrays
Syntax and usage
Accessing array components
array subscripting operator [ ]
How to use for loops to access array elements
for (i = 0; i < 100; i++)
Initialization: list[i] = 0.0;
read data: cin >> list[i];
Print data: cout << list[i];
Search a key item from the array
find the sum, average, largest
See lecture slides
int num[5];

15. Chapter 9: Arrays and Strings* (cont'd)
Array initialization during the declaration
double sales[] = {12.25, 32.50, 16.90, 23, 45.68};
int list[10] = {0};
int list[10] = {8, 5, 12};
int list[] = {5, 6, 3};
int list[25]= {4, 7};
See lecture slides
Restrictions of array
Does not allow aggregate operations
Must use for loop to copy from one array to another

16. Chapter 9: Arrays and Strings* (cont'd)
C-String (character array)
C-strings are null-terminated ('\0') character arrays
Declaration and initialization
char name[16] = "John";
char name[] = "John";
Access the character in the C-String
name[0] ~ name[3]
'\0' is not counted at the length of the C-String
Parallel arrays
Two (or more) arrays holding related information in the corresponding components
2-dimensional arrays
