Check palindrome with two pointers alternate method

Given a string , check whether the reverse read of the string is same and print as "palindrome" if it does else print "not a palindrome" using two pointers with one pointer pointing to the starting index of the string and other pointer pointing to the ending index of the string.

#include <stdio.h>
int main(void) {
   char *s,*e,x;
   int flag=1;
   s=(char*)malloc(sizeof(char));
   scanf("%s",s);
   e=(s+strlen(s)-1);
   x=e;
   if(strlen(s)>2)
   {
     while(s!=e && s==x)
     {
      if(!(*s==*e))
      {
        flag=0;
        break;
      }
      s++;
      e--;
            x=e;
      x--;
     }
   }
   else if(*s!=*e)
    flag=0;
   if(flag)
    printf("palindrome");
   else
    printf("not palindrome");
   return 0;
}
