When do we use void?

Question

In the tutorial apparently we used int instead of void to make a function with multiple parameters.

Answer 1

void is used when nothing has to be returned.
Eg.

void hello (int i)
{
cout <<i;
}
int main
{
hello(1);
}

Answer 2

when we do not want to return anything 🐈

Answer 3

Void used when you do not want to return any values from function. You always must declare type of value you want return and void is like "nothing returns".

Answer 4

Usually when you want to print something without returning anything

Answer 5

When we don't have to return anything.
