Question

say I have an if statement as such

if(condition1 || condition2 || condition3)
{
 //do something
}

Is it possible to find out which of the 3 conditions was true when we enter the loop?

Answer 1

Yes, you can check each one individually with something like:

if(condition1 || condition2 || condition3) {
    if (condition1) { doSomethingOne(); }
    if (condition2) { doSomethingTwo(); }
    if (condition3) { doSomethingThree(); }
    doSomethingCommon();
}

assuming of course that the conditions aren’t likely to change in the interim (such as with threading, interrupts or memory-mapped I/O, for example).
