C++ If statements in a do while loop with a yes or no ending

really new to coding...as in I didn't know anything at all until about 2 weeks ago. I am trying to do a long do while loop with nested if statements but I'm having issues with getting my loop to actually loop.

Instead of getting help directly on my project, which is a very long code, I made a simple kind of like it version. It also does not loop. It will get to the end and ask the user if they want to try again but when "y" is entered it ignores the if statements.

#include <iostream>
#include <string>
using namespace std;

int main()
{
    string sodaChoice;
    char answer = 'n';

    do
    {
        cout << "Please choose your favorite soda from the following: Rootbeer, Diet Coke, Coke, Sprite" << "\n";
        getline(cin, sodaChoice);

        if (sodaChoice == "Rootbeer")
        {
            cout << "Me too!" << "\n";
        }
        else if (sodaChoice == "Diet")
        {
            cout << "Not me :(" << "\n";
        }
        else if (sodaChoice == "Coke")
        {
            cout << "It's alright" << "\n";
        }
        else if (sodaChoice == "Sprite")
        {
            cout << "only if I'm sick" << "\n";

        }
        else
        {
            cout << "That was not on the list";
        }
        cout << "would you like to try again?";
        cin >> answer;



    } while (answer == 'y'|| answer == 'Y');




    return 0;
}

I thought maybe I needed a do loop in the do loop around the if statements but then I didn't know how to go about it. Any help would be appreciated. I have spent many, many hours trying to figure it out.

I tried to ask my teacher, but my college teaches from some generic curriculum that their dean wrote based on HER book. He is not very enthusiastic about helping or teaching.

Which brings me to a second off topic question. I have been basically learning coding on my own through online tutorials, do I have to have the degree to get a good job, or do certificates count? (I have a bachelors in Business Management).
