    ans = num1 / num2;
    
    cout << "Quotient: " << ans << endl;
    
    return(ans);
    
}


I'm trying to get it to where it'll do an actual loop until the user is done making calculations.

All help will be very much appreciated!

You test while(yesNo = 0), using the assignment (=) operator, and not an equality check (==). The assignment operator will return a reference to the number itself (0), which is equal to false in c++. Change this to the == operator. Also, you can probably just check while(yesNo), since a 0 is false and anything else is true (You tell the user to input yes=1 and no=0).
