Read about return values of isgraph function .

1st Parameter Type : int

Integer type (typically 4 bytes, -2,147,483,648 to 2,147,483,647)

1st Parameter

The character to be tested, passed as an `unsigned char` cast to an `int`, or `EOF`

The isgraphfunction in C language Checks whether the character has a graphical representation.

The isgraph function tests whether c is a character with a graphical representation. In the default C locale, it includes all printing characters except space.

The isgraphfunction takes 1 parameter:

•
int `c`: The character to be tested, passed as an `unsigned char` cast to an `int`, or `EOF`

Checks if the given character `c` has a graphical representation, meaning it is a printable character excluding the space character (`' '`). Returns a nonzero value if `c` is a graphical character, and `0` otherwise.

The isgraph function return value :

Returns non-zero if the character has a graphical representation, 0 otherwise

Output

This example demonstrates basic usage of isgraph with various characters.
