The getchar() function is to get an unsigned character from the computer terminal (usually the keyboard). The getchar() function can only receive one character, and its function value is the character obtained from the input device.
getchar function syntax
(1)Function declaration
int getchar(void)
(2)Parameter
NA
(3)Function
C library function int getchar(void) gets a character (an unsigned character) from the standard input stdin. This is equivalent to getc taking stdin as argument.
(4) Return value
This function returns the read characters in the form of unsigned char cast to int. If the end of the file is reached or a read error occurs, EOF is returned.
(5) Usage
This function is declared in the stdio.h header file, and the stdio.h header file must be included when using it. Such as:
#include<stdio.h> int getchar(void);
