Thread: Test Palindrome

HI,

My goal is to write a program to test if a particular string is a palindrome (string that's spelled the same way backwards and forwards ). Here is the code but it doesn't work, it always return false, i don'tk now why, pls tell me whats wrong, thnx in advance!

Code:

/* Palindrome */

#include <stdio.h>

int testPalindrome( char array[] );

int main()
{
   char string[ 6 ] = "ellle";

   if ( testPalindrome( string ) == 1 )
      printf( "String is a palindrome.\n " );
   else if ( testPalindrome( string ) == 0 )
      printf( "String is not a palindrome.\n" );

   getch();

   return 0;
}

int testPalindrome( char array[] )
{
   int length = 0;
   int i = 0;

   i = 0;

   while ( array[ i ] != '\0' ) {
      ++length;
      i++;
   }

   if ( length - 1 == 0 || length - 1 == 1 )
      return 1;
   else if ( array[ 0 ] != array[ length - 2 ] )
      return 0;
   else {
      array[ 0 ] = '\0';
      array[ length - 2 ] = '\0';
      for ( i = 0; i < 6; i++ )
         printf( "%c", array[ i ] );

      return testPalindrome( array );
   }
}
