Lesson 84/120

The return statement terminates function execution and sends a value back to the caller.

RETURNING A VALUE

int square(int x) {
    return x * x;
}

Using the return value

int result = square(5);
cout << result; // 25

SINGLE RETURN

A function can only return ONE value. To return multiple, use pointers, references, structs, or std::pair.

VOID RETURN

Use return; without a value to exit a void function early.
