Void

Question

what us void ?

Answer 1

Void as a return value means that the function doesn't return anything. For example:

void printn(int n) {
cout << n << endl;
}

When void is in the parameter field, it means that the function doesn't take any parameter. For example:

int getAnswer(void) {
return 42;
}

Answer 2

no return value

void print()
{
cout<<"Hello world";
