Ok so i hasve a class and i cant access a string or another variable for some reason, what am i doing wrong? im trying to use name and age in main. also in save.

#include <iostream>
#include <string>

using namespace std;

class Vars
{
    public:
        void Bank();
        void Save();
        Vars()
        {
            money = 0;
            level = 1;
            name;
            age;
        }
    private:
        int money;
        int level;
        int age;
        string name;
};


int main()
{
    Vars VO;
    VO.age;
    string choice;

    cout << "New" << endl;
    cout << "Load\n" << endl;
    cin >> choice;

        if(choice == "New" || choice == "new")
        {
            cout << "Please enter your name\n" << endl;
            cin.ignore(556, '\n');
            getline(cin, name);
            cout << "\n";

            cout << "Ok thanks " << name << " What is your age?\n" << endl;
            cin >> age;
            cout << "\n";

            cout << "Ok so your name is " << name << " and your " << age << " years old" << endl;

            cin.get();

            VO.Bank();
        }
        else if(choice == "Load" || choice == "load")
        {

        }
}


void Vars::Bank()
{

{
    Vars VO;

    ofstream file("Bank.txt");

    file << name << endl;
    file << age << endl;
}

Do you know what public, protected and private do?

[Ch1156]

Im familiar with public and protected but not sure about private, ever heard of it before.

[ne555]

¿why do you use it, then?

[expor]

Try going through the errors and warnings one by one for starters?

Line 15: Just naming a variable and doing nothing has no use at all. You're not initializing it nor declaring it.
Line 16: Same as line 15.

Line 21: You declared money, level, age and name as private. As kbw said, look up what public, protected and private do.

Line 29: Bit like 15 and 16, you just name a variable from an object, you don't change it, you don't output it, just named it.

Line 40: You try to copy user input into a non-existing variable. Either declare the variable, or (as you probably wanted), use the object's name property (after fixing the private issues in your class).
Line 44: Same as line 40.

Line 69: You need to #include <fstream>
