Answer 2

Hi,
getchar is a function in C programming language that reads a single character from the standard input stream stdin, regardless of what it is, and returns it to the program. It is specified in ANSI-C and is the most basic input function in C. It is included in the stdio. h header file.
int getchar() = Returns the next character from the standard input (stdin). Basically read one character at a time. ... It allows you to deal with any type of input/output without knowing their exact data type
