isgraph - Test for printable character except space

Definition	#include <ctype.h> int isgraph(int c); isgraph checks whether the character c is a printable character, i.e. an alphanumeric or a special character. Spaces are considered to be non-printable. c is the value of the character to be checked.
Return val.	!= 0 0	c is printable and not a space. c is non-printable or space.
Note	isgraph is implemented both as a macro and as a function (see section“Functions and macros”).
Example	#include <ctype.h> #include <stdio.h> int main(void) { int c; while((c = getchar()) != EOF) printf("%s : %c\n",((isgraph(c))? "Character" : "Cannot print"), c); return 0; }
