Advanced Input, Process and Output Commands Session 3

 Input  scanf(“%d”,&a);  gets(nm_mhs);  sex = getch();  Output  printf(“%d”,a)  puts(“Nama Anda : “+nm_mhs);  putchar(sex); Input – Output Command

 %d is called Format Specifier  Use of determining the format is associated with the type of data to be printed, meaning each has a data type determines the format of each. The following table is a table determines the format for each type of data. Format Specifier

 Character combinations consisting of a backslash (\) followed by a letter or by a combination of digits are called "escape sequences." To represent a newline character, single quotation mark, or certain other characters in a character constant, you must use escape sequences. An escape sequence is regarded as a single character and is therefore valid as a character constant. Escape Sequences

 Escape sequences are typically used to specify actions such as carriage returns and tab movements on terminals and printers. They are also used to provide literal representations of nonprinting characters and characters that usually have special meanings, such as the double quotation mark ("). The following table lists the ANSI escape sequences and what they represent. Escape Sequences

Table of Escape Sequences Escape SequenceRepresents \aBell (alert) \bBackspace \fFormfeed \nNew line \rCarriage return \tHorizontal tab \vVertical tab \'Single quotation mark \"\"Double quotation mark \\Backslash \?Literal question mark \oooASCII character in octal notation \xhhASCII character in hexadecimal notation \xhhhh Unicode character in hexadecimal notation if this escape sequence is used in a wide-character constant or a Unicode string literal. For example, WCHAR f = L'\x4e00' or WCHAR b[] = L"The Chinese character for one is \x4e00".

Create a program to calculate the sum and difference of two integers, then show the sum and difference was to use wide-format field = 8. Input data: number 1, number 2 Data output: total, difference The desired view as follows: Enter Number 1: Enter Number 2: The number between... and... are: The difference between... and... are: Task 3
