C++ Short Hand If Else

Short Hand If...Else (Ternary Operator)

There is also a short-hand if else, which is known as the ternary operator because it consists of three operands. It can be used to replace multiple lines of code with a single line. It is often used to replace simple if else statements:


variable = (condition) ? expressionTrue : expressionFalse;

Instead of writing:


int time = 20;
if (time < 18) {
  cout << "Good day.";
} else {
  cout << "Good evening.";
