Thread: Variables between functions?

Hi, I'm a little confused and was hoping someone could help me tidy up this problem. I'm trying to write a program which allows the user to input an address, which then prints it on the screen, and finally sends it to a label printer. The problem I've got is that I've just discovered that variables aren't passed between functions.

I need addressenter() to pass the address to the other functions like menu(), and printlabel()

How do I do this? I've misunderstood the tutorial I think, so I'd grateful if you could clear it up for me.
Thanks

Sorry this is a real shambles, but I can sort it out once I know what to do.

Code:

#include <iostream>

using namespace std;

// prototype address enter function
int menu();
void printlabel();
void addressenter();

int main()
{

    cout<<"This program prints single address labels input by the user.\n\n";
    addressenter();
    print();

    cin.get();
}

// post-addressenter menu
int menu()
{
        x = 0;
    cout<<"\n\nYour address was: \n\n";
     while (x<y) {
        //Address output here
        cout<<address[x]<<endl;
        x++;
    };
    cout<<"\nThe address has to be truncated to 22 chars, is it correct?\n1. Yes\n2. No\n\n";
    int m;
    cin>>m;
    if ( m == 1 ) {
        cout<<"Print label...";
    }
    else if ( m == 2 ) {
        cout<<"Reenter address";
        addressenter(1);
    }
    else {
        cout<<"Invalid selection, please try again.\n";
        menu();
    };
    return 0;
}

int addressenter()
{
    // address enter function
    // str length is 23 as 22+terminating.char "\0"
    string address[7];
    string addressin;
    cout<<"Enter the address to be printed.\n";
    int x = 0;
    int y = 0;
    while (x<7 && y!=1) {
        //Address input here
        cout<<"Line "<< x + 1 <<": ";
        //cin.getline ( address[x], 23, '\n' );
        getline(cin, addressin);
        if (addressin!="") {
        address[x] = addressin.substr(0, 22);
        x++;
        }
        else {
            y=1;
        };
    };
    y = x;
    x = 0;
    cout<<"\n\nYour address was: \n\n";
     while (x<y) {
        //Address output here
        cout<<address[x]<<endl;
        x++;
    };
    menu();
    return 0;
}
