putchar - Write a character to the standard output

Definition	#include <stdio.h> int putchar(int c); putchar writes the character c to the standard output.
Return val.	The written character c
		if successful.
	EOF	otherwise.
Notes	putchar is implemented both as a macro and as a function (see section “Functions and macros”). The characters are not written immediately to the external file but are stored in an internal C buffer (see section “Buffering” (Basic terms)). For further information on output to text files and on converting the control characters for white space (\n, \t, etc.) see section “White space” (Basic terms).
