     void main()
      {
       char a[50] , b [50];
       int x;
       clrscr();
       printf("Enter string  ");
       gets(a);
       strcpy(b,a);
       strrev(b);
       x = strcmp(a,b);
       if ( x == 0)
       {
 printf("it is a palindrome");
 }
       else
       {
       printf(" it is not palindrome");
       }
       getch();
       }
