    if you want to simplify something you can start from using if (startDate) instead of if (startDate == true) :) Commented Mar 7, 2019 at 19:54

    I would strongly question whether avoiding variables in C is a good idea. C compilers are generally good at optimizing out locals. Commented Mar 7, 2019 at 20:59

    "I know some languages (C comes to mind) its best to declare as few variables as possible" - honestly, this sounds like a very unfounded, superstitous believe to me, do you have any references for this strange recommendation? Who told you this? Commented Mar 7, 2019 at 21:18

    For readability's sake, startDate is a terrible name for a Boolean variable. If I randomly saw startDate somewhere in a block of code and did not see the type declaration, Boolean would definitely not be the type I'd infer. Commented Mar 7, 2019 at 21:58

    "I know some languages (C comes to mind) its best to declare as few variables as possible" - That's just wrong, and you can easily see why, because the compiler will typically produce the exact same assembly, at least when you provide the usual optimisation flags.
