C++ getchar() Function

getchar( ) is a function that takes a single input character from standard input. The major difference between getchar( ) and getc( ) is that getc( ) can take input from any number of input streams but getchar( ) can take input from a single standard input stream.

It is present inside the stdin.h C library. Just like getchar, there is also a function called putchar( ) that prints only one character to the standard output screen

Syntax:

int getchar(void);

Return Type: The input from the standard input is read as an unsigned char and then it is typecasted and returned as an integer value(int) or EOF(End Of File). A EOF is returned in two cases, 1. when file end is reached. 2. When there is an error during execution.
