Why can't i compare characters like this?

thnx

#include <stdio.h>

int main()
{
   char c = 'X';
   char c2 = 'X';
   char c3 = 'X';

   if ( c == c2 == c3 )
      printf( "Compared successfully" );

   system("PAUSE");
   return 0;
}

Here's a clue

int main()
{
   char c = 'X';
   char c2 = 'X';
   int c3 = 1;//What!!!!!

  if ( c == c2 == c3 )
      printf( "Compared successfully" );

   system("PAUSE");
   return 0;
}

In your example, it will return false, according to my theory, but in my example, it'll return true. But sinze that's not the case, i don't know what's wrong with it.

I hope you can explain.

thnx

Wait, i think i got it.

When i compare this:

c == c2

if they are equal they return 1, indicating true,

when it's compared to c3 like this

c2 == c3,

it's actually comparing c3 with 1 like

c3 == 1


am i right this time?

thnx

You win the prize!

So, to do what he wants to do it would be

if (ch1==ch2 && ch2==ch3)
....

right?
