no compiler errors, but no place for input

[monacorona]

I'm trying to build a program that functions as a beverage survey, and while it compiles with no errors--it automatically adds up the tally without asking for votes, which results in everything adding up to 0.

Instructions:
Write a program that performs a survey tally on beverages. The
program should prompt for the next person until a sentinel value of –1 is
entered to terminate the program. Each person participating in the survey
should choose their favorite beverage from the following list:

1. Coffee 2. Tea 3. Coke 4. Orange Juice


Here's the code:

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

int main()

{
    int choice, coffee = 0, tea = 0, coke = 0, orangeJuice= 0, personNumber = 1;
    
    cout << "Beverage Survey\n" << endl;
    cout << "Which of the following beverages would you consider to be your favorite?\n" << endl;
    cout << "1. Coffee " << endl;
    cout << "2. Tea " << endl;
    cout << "3. Coke " << endl;
    cout << "4. Orange Juice " << endl;
    cout << endl;
    
    while (choice > 0)
    {
        cout << "Input favorite beverage of person # ";
        cin >> personNumber;
        cout << " Choose 1, 2, 3, or 4 from the above menu or -1 to exit the program" << endl;
        cout << endl;
       
        personNumber++;
        switch(choice)
        {
                
            case 1:
                coffee++;
                break;
            case 2:
                tea++;
                break;
            case 3:
                coke++;
                break;
            case 4:
                orangeJuice++;
                break;
            default: cout << "Please choose one of our available menu items";
                cin >> choice;
        }
    }
    
    cout << endl;
    
    cout << "The results are as follows:\n" << endl;
    cout << "Beverage of choice:" << setw(40) << "Number of votes:" << endl;
    cout << "-----------------------------------------------------------------------" << endl;
    cout << "Coffee:"     <<    setw(32) << coffee << endl;
    cout << "Tea:"        <<  setw(35) << tea << endl;
    cout << "Coke:"       <<   setw(34) << coke << endl;
    cout << "Orange Juice:"  << setw(26) << orangeJuice << endl;
    
    return 0;
    
}

Look at line 9, then line 19, see if you can figure out the problem.
