Thread: What is wrong with this program ?

hi,

after i ran this program it shows nothing, i have to use control + c to quit. I use debugger and it generate errors. How come, Pls tell me why thnx a lot.

Code:

#include <stdio.h>

int palindrome( char string[] );

int main()
{
   char string[ 5 ] = "elle";

   if ( palindrome( string ) == 1 )
      printf( "It IS a palindrome." );

   getch();
   return 0;
}

int palindrome( char string[] )
{
   int i = 0, length = 0;

   while ( string[ i ] != '\0' )
      ++length;

   if ( length - 1 == 1 || length - 1 == 0 )
      return 1;
   else if ( string[ 0 ] != string[ length - 2 ] )
      return 0;
   else {
      string[ length - 2 ] = '\0';
      return palindrome( &string[ 1 ] );
   }
}
