Hjælp til c++

Jeg er ved at kode lidt c++. og når jeg starter mit script virker det fint lige indtil men svarer.

Mit script ser sådan ud:
#include <iostream>

int main() {
    int YN;
    int y;
    int n;

   
    start:

    std::cout << "Do you want me to white hej. y or n" << std::endl;

    std::cin >> YN;
    std::cout << "You typed" << YN << "" << std::endl;
    if (YN == y) {
        goto print;
    } else if (YN == n) {
        goto end;
    } else {
        std::cout << "ERROR" << std::endl;
        goto start;
    }





    print:
    system("echo hej");
    goto end;


    end:
    system("exit");
    return 0;
}

Log'en ser sådan her ud:
