Return
Previously we used functions like action makers, we gave the parameters (or no), and the function did some actions we wanted.
However, the keyword void
, which we used in previous examples, shouldnβt return a value. If you want the function to return any values, you have to specify the type of value you want to get instead of void and use the keyword return
. For instance:
12345678910// Declaration of the function int sum(int a, int b) { return a+b; } int main() { // Call the function to be executed cout << sum(4, 5); return 0; }
Here the function sum()
gets 2 integer values and returns their summary (sum) - integer value, so before the declaration, we use int
.
The function firstly returns the value, and then we print it in the main
function.
