Loading c++ source code from .txt file

void checkSettings()
{
    string STRING;
    ifstream infile;
    infile.open("C:\Users\Jakereid\Desktop\Settings.txt");
    while (!infile.eof) 
    {
        getline(infile, STRING);
        cout << STRING;
    }
    infile.close();

}

So I have a function called checkSettings, and it was just a long list of setmenu values: 

menu.setValue(Tab_Menu, Menu_Custom2, 0);

It worked perfectly when it was in the source code under check settings, but what I want to do now is when the application starts is to load what ever is in the current settings.txt fileinto the check settings function. So what I want to do is to be able to have:

void checkSettings()
{
  Contents of the .txt file
}

I've tried following a few different tutorials but have had no luck. Thank you :)

You cannot do this with C++ directly. C++ is a compiled language. What you can potentially do is call your settings file in a different language. For eg, there is a boost interface to call python scripts from c++.

You may also be able to use Lua.

Since these are not compiled languages, the code in your settings file can differ, and this will still work.

This will not work directly because C++ is a compiled language, and the settings file is different in each environment.

Instead, you should parse the settings file in your code and load the settings based on it.
