String Palindrome using pointers

#include<stdio.h>

int string_palindrome(char *s)
{   
    char *p;
    p=s;
    while(*p!='\0')
    {
      *p++;
    }
      p--;
    
    while(*s!='\0')
    {
        if(*s!=*p)
        {   
            return 1;
        }
        s++;
        p--;
    }
    
    return 0;
}


main()
{   char a[100];
    int l,flag;
    printf("Enter a string\n");
    gets(a);

    flag=string_palindrome(a);
    if(flag==0)
    {
        printf("String is palindrome");
    } else
    {   printf("String is not palindrome");
    }
}
