oh and just to clarify, it does it when i exit the program then start it back up and choose option 2. it just gives me weird numbers.

Look at the name of the file that you are saving to and the name of the file you are reading from.

        ofstream file;
        file.open("prison.txt");

3
 
        ifstream file;

        file.open("file.txt");


... they need to be the same file...
change that and it runs nicely.


Just a suggestion, try making the part of the code that loads the file info into a function named "Load()" in your vars struct so that you can call it at any time you want. like I said, just a suggestion.

    void Load();

    long long int money;
    int prisoners;
    string playerName;

};

void Load()
{
    ofstream file;
    file.open("prison.txt");

       file.open("file.txt");

        file >> v.playerName;
        file >> v.prisonName;
        file >> v.money;
        file >> v.prisoners;

        file.close(); 
}
