Multiple functions in a C++ program

[nicckk]

This is my first day of C++ and I was wondering how to get multiple functions in a C++ program. Any help would be appreciated. Here is my source.

#include <iostream>
using namespace std;

int main()
{
    char number;
    cout << "Please input a value\n"; 
    cin >> number;
    cout << " You selected: " << number; 
    second(); // This should work in a C program, how do I do it in C++
    system("PAUSE");
    return 0;
}
      
int second() // This is where I run into problems
{
    char number;
    cout << "Please select another value...";
    cin >> number;
    cout << "You selected: " << number;
}

Thanks

You have to declare second() before you can call it.

// Value selector
// Nick Dichev 2009

#include <iostream>
using namespace std;

int second() ;
int main()
{
    char number;
    cout << "Please input a value\n"; 
    cin >> number;
    cout << " You selected: " << number; 
    second(); // This should work in a C program, how do I do it in C++
    system("PAUSE");
    return 0;
}
      
int second() // This is where I run into problems
{
    char number;
    cout << "Please select another value...";
    cin >> number;
    cout << "You selected: " << number;
}

Thanks Winged, that worked. But the compiler then told me I needed a semi-colon before the int main(). I plugged it in and it worked fine. Can you describe why? I thought that a semi-colon ended a line of code?

Thanks

int second();

declares a function, and must end with a semi-colon, just like any other declaration (such as int

i;

).
