Question

I used following code..but i am looking for proper condition to put. please help me out with it.

int main(){
    int k = 0;
    char a[9] = {'\0'}, b[9] = {'\0'};

    printf("enter string \n");
    gets(a);
    int p = strlen(a);

    for(int i = p-1; i >= 0; i--){
        b[k] = a[i];
        k = k+1;
    }

    for(int j = 0; j < p; j++){
        if(a[j] == b[j]){
            continue;
        }else
            printf("not pal");

        break;
    }
    return 0;

Answer 1

for(int j=0;j<p;j++)
{
      if(a[j]!=b[j])
      {
          printf("not pal");
          return 0;
      }
}
printf("string is Palindrome");
return 0;
