#include <stdio.h>
#include <ctype.h>

int main()
{
    int cnt;
    printf("Punctuation marks are: \n");

    for (cnt = 0; cnt <= 127; cnt++)
        if (ispunct(cnt) != 0)
            printf("%c ", cnt);

    printf("\n");

    return 0;
}

Output

Punctuation marks are: 
! " # $ % & ' ( ) * + , - . / : ; < = > ? @ [ \ ] ^ _ ` { | } ~
