   printf("\nEnter the string: ");
   gets(a);
   n=strlen(a);
   for(i=0;j=n-1;i<=j;i++;j--){

    }
   }
   if(i==j){
    printf("\nThe string %s is a palindrome",a);
   }
   getch();

Answer 1

Your problem is that the line for(i=0;j=n-1;i<=j;i++;j--){ has too may semicolons in it!

Semicolons separate statements and for takes only three such. To put two (or more) expressions in the same statement, separate them with commas, as follows: for(i=0, j=n-1; i<=j; i++, j--){

Hope this helps.
