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:
Syntax
variable = (condition) ? expressionTrue : expressionFalse;
Instead of writing:
Example
int time = 20;
if (time < 18) {
cout << "Good day.";
} else {
cout << "Good evening.";
}
if (time < 18) {
cout << "Good day.";
} else {
cout << "Good evening.";
}
You can simply write:
Example
int time = 20;
string result = (time < 18) ? "Good day." : "Good evening.";
cout << result;
string result = (time < 18) ? "Good day." : "Good evening.";
cout << result;
