Question

Say I have a structure as follows

struct stock{
    string ticker;
    double price;
    double volume;
    double eps;
};

If I want to output one of the variables such as price when asked for it would I have to do a large if/else or switch statement to match up the user input with the member or is there a more elegant way to do it because I know stock.userInput does not work.

there’s no special keyword to find your variable(sorry to burst your bubble), You would have to use a logical statement. It would go along:

cout << "What would you like to see? (1)Price (2)etc...etc...";
cin >> input;
switch(input)
{
    case 1:
        cout << Obj.Price;
    break;
    case 2:
        cout << //....
    break;
}

I personally like using keys and a switch statement, it tends to be a lot cleaner and easier to go back and modify later in the program.
