Why can't a function go after Main

Question

Why can\'t I put a function after main, visual studio cannot build the program. Is this a C++ quirk or a Visual Studio quirk?

eg.

int main()
{
   myF         


        

Answer 1

you have to forward declare a function so main can know that there is some.

void myFunction();

int main()
{
   myFunction();
}

void myFunction(){}

Don't forget about putting ; after each command.

Answer 2

You have to declare the function before.

void myFunction();

int main()
{
    myFunction()
 }

 myFunction(){}
