• == and =
• if

	main()
	{
	   int left=10;

	   if ( left = 5 )
	   {
	      puts(" Values are equal...");
	   }
        }

The program assigns 5 to the variable left and returns 5. This is interpreted as TRUE and causes the puts statement to be executed everytime.

Here is the corrected program.

	main()
	{
	   int left=10;

	   if ( left == 5 )		/* Double equals required. */
	   {
	      puts(" Values are equal...");
	   }
        }
