Thread: C++ newbie problem!

Hello guys!

First I'd like to say that I started studying C++ just a few days ago with the HUGE help of Alex Allain's guide.

Now, I've learned some basics (I'm currently at lesson 16 of Alex's guide) and I started to write a small text game of my own. I got through the beginning well, but then a problem arose.

I'll link the code first and point out the part I have problem with.
So here's the code (scroll below the code to see my problem):

Code:

#include <iostream>#include <cstring>
using namespace std;
int input;
char string[256];
void line()
{
    cout<<"-------------------";
}
void game1()
{
    cout<<"Welcome to the world of whatever (this is just and example for the forums)"<<string<<"!"<<endl;
}
void game0()
{
    char string[256];
    cin.getline(string, 256, '\n');
    cout<<"Please enter your name: ";
    cin.getline(string, 256, '\n');
    cout<<endl;
    cout<<"Confirm name: "<<string<<"? (yes/no): ";
    cin.getline(string, 256, '\n');
    cout<<endl;
    if (strcmp(string, "yes")==0)
    {
        game1();
    }
    else if(strcmp(string, "no")==0)
    {
    cout<<"Please re-enter your name correctly: ";
    cin.getline(string, 256, '\n');
    game1();
    }




}
void instructions()
{
    cout<<endl;
    cout<<"Instructions:"<<endl;
    cout<<"-------------"<<endl;
    cout<<endl;
    cout<<"Always press ENTER to progress."<<endl;
    cout<<endl;
    cout<<"If you are prompted to answer either yes or no"<<endl;
    cout<<"make sure your grammar is correct. Only use lower-"<<endl;
    cout<<"case letters in these cases or the game will crash."<<endl;
    cout<<endl;
    cout<<"Everything else is pretty self-explanatory."<<endl;
    cout<<endl;
    cout<<"Press ENTER to move back to Main Menu."<<endl;
    cout<<endl;
    cin.ignore();
    cin.get();


    cout<<"Test game!"<<endl;
    cout<<endl;
    int input;
    cout<<"1.Start game"<<endl;
    cout<<"2.Exit"<<endl;
    cout<<"3.Instructions"<<endl;
    cout<<endl;
    cout<<"---------"<<endl;
    cout<<"Selection: ";
    cin>>input;
    cout<<"---------"<<endl;
    cout<<endl;
    switch (input)
    {
        case 1:
        game0();
        break;
        case 2:
        cout<<"Exiting program."<<endl;
        cin.ignore();
        cin.get();
        break;
        case 3:
        instructions();
        break;
    }


}
int main()
{
    int input;
    cout<<"Test game."<<endl;
    cout<<endl;
    cout<<"1.Start game"<<endl;
    cout<<"2.Exit"<<endl;
    cout<<"3.Instructions"<<endl;
    cout<<"---------"<<endl;
    cout<<"Selection: ";
    cin>>input;
    cout<<"---------"<<endl;
    cout<<endl;
    switch (input)
    {
        case 1:
        game0();
        break;
        case 2:
        cout<<"Exiting program."<<endl;
        cin.ignore();
        cin.get();
        break;
        case 3:
        instructions();
        break;
    }


}

First of all, I know I'm using a lot of useless stuff in there but this is my first project so all that matters to me is that it works as intented.

Anyway the problem is that I want to use the name defined in void game0() later on in the game by using the string's definition but I can't because it's defined in another void.

So my question is: is there any way I could use the string defined in void game0() in other voids through some coding?

Thanks in advance. And I'm sorry if this question has already been answered in another thread. I tried looking through the forums, but couldn't find an answer.

Thank you for your effort oogabooga!
As expected I can't get that code to work due to my lack of knowledge.
I will continue my studies and come back to this project when I've learned some more.
Nevertheless I appreciate you answering, and I'm sorry I couldn't put your advice to use.
