isprint - test for printing character

Syntax

#include <ctype.h> int isprint(int c);

Description isprint() tests whether c is a printing character, i.e. an alphanumeric character, a special

	character, or a space. In all cases, the argument c is an int, the value of which must be representable as an unsigned char or must equal the value of the macro EOF. If the argument c has any other value, the behavior is undefined.
Return val.	!= 0 0	Printing character (alphanumeric, special character or space). Non-printing character
Notes	isprint() is implemented both as a function and as a macro. To generate a function call, the definition of the macro name must be first undefined (#undef isprint). The behavior of isprint() is determined by the class print of the current locale. The current locale is the C locale, unless it was explicitly changed using setlocale().
