bool check() { Console.WriteLine("Called"); return false; }
if (false && check()) { } // check() never runs. && stops at first false
if (true || check()) { } // check() never runs. || stops at first trueUse this to prevent errors: if (user != null && user.IsActive)
int cartTotal = 1200;
bool isFirstOrder = true;
bool hasCoupon = false;
bool applyDiscount = cartTotal > 1000 && (isFirstOrder || hasCoupon);
// true: cartTotal > 1000 is true, isFirstOrder is trueEasy Q1: What does 10 % 3 return?
Medium Q1: int x = 5; Console.WriteLine(x++); prints?
Hard Q2: Will Check() run? if(false && Check())
