The ispunct function tests whether c is a printing character for which isspace and isalnum return false. In the default C locale, it includes all printing characters that are not alphanumeric or space.

The ispunctfunction 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` is a printable punctuation character. Returns a nonzero value if `c` is a punctuation character, and `0` otherwise.

The ispunct function return value :

Returns non-zero if the character is a punctuation character, 0 otherwise
