2+3 and 5 Are Not Equal in C

Question: 2+3 and 5 are not equal In C Program.. How?:

#define Square( X ) ( X * X )
void main( )
{
	int value1,value2;

	value1 = Square( 2+ 3 );
	value2 = Square( 5 );

	if ( value1 == value2 )
		printf("Equal");
	else
		printf("Not Equal');
}

Output:

Not Equal.

Description:

The Macro replaces the code when there is necessity of the code.From the above program, we can able to understand the usage of Macro.

The value of value1 = 11.

The value of value2 = 25.

How ?

When the code Square(X) (X*X) replaces,we get,

Iteration 1:

value1= (2+3*2+3)

Therefore,value1=11.

Iteration 2:

value2= 5 * 5

Therefore,value2= 25.

Conclusion:

So, we come to a conclusion that 2+3 and 5 is not equal always.

And hence,the Macro should be used in appropriate situations,otherwise Macro will give wrong result.
