However, it depends what you want to do next. You could just do something like this:
5 < 3;
Hardly very useful.
Or perhaps something like
bool result = 7 == 4;
which is potentially useful - you could later do something with the variable result, such as print it out.
Or if you want to take some action after the compare, then the conditional ternary operator ( ? ) is a possibility - but that really fits in a very specific context and isn't a general-purpose replacement for anything else. http://www.cplusplus.com/doc/tutorial/operators/
