Getting started with Functions in C++

 #include <iostream>

using namespace std;

void sayHello() {

    cout << "Hello :)\n";

}

int main() {

    sayHello(); // function call

    return 0;

}

Hmmm interesting....

#include <iostream>

using namespace std;

void sayHello() {

    cout << "Hello :) \n";

}

void assistant() {

    sayHello();

    cout << "work done \n";

}

int main() {

    assistant();

    return 0;

}
