[C++][7] Functions

#include <iostream> //pre-processor directive

using namespace std; //std library

void printSomething(); //prototype a function so that the function is called 1st

int main() //it starts with the main 1st
{
    printSomething();
    return 0; //to tell that program ran fine
}

void printSomething(){ //function

    cout<< "text on screen" <<endl;
}

//C++ works from top to bottom so unless the function is called 1st or there is a function prototypr before main, the program would not run properly
