Just to clarify what he said, in C any non-zero value is true. Zero is false. So, if you had a variable and you wanted to test if it was zero, you could say:

    if(!variableBeingTested)
    {
    	// Variable is zero
    }
    else
    {
    	// Variable is not zero
    }

It is considered better form by most people, however to explicitly put in the test for zero. For example:

     if(variableBeingTested == 0)
     {
     	// Variable is zero
     }
     else
     {
     	// Variable is not zero
     }
