Relational Operators

List of operators

Purpose	Operator example
less than	x < y
less than or equal	x <= y
greater than	x > y
greater than or equal	x >= y
equal	x == y
not equal	x != y

• zero is false and non-zero is true

• Warning: a common mistake is
  

        int i, j;
        /* some code setting i and j */
        if ( i = j )
        { /* some stuff */
        }
  

  this sets i = j and then does some stuff if j is non-zero
