While Loop statement help (not hacking related AT ALL.)

int main()
{
    int c=100, b=1;
    char choice='y';
    //char AnotherChoice='x'; //this line is useless.. commented
    cout << "Welcome to our store! Would you like to buy a bread for 1 coin? <y/n> ";
    cin >> choice;
    while(choice=='y' && c >= 1) //something you forgot.. u must have enough money!
    { // you forgot it.. thats why it was outputting the bad message without asking because it loops through the if statement only
        //another useless while, it will never step here if it is not y : )
        //if(AnotherChoice=='y')
        //{
        c--;
        c++;
        cout << "Here you go! " << endl;
        //}
        cout << "COINS: " << c << endl;
        cout << "BREAD: " << b << endl;
        cout << endl;
        cout << "Would you like to buy another bread for 1 coin? <y/n> ";
        //you forgot to ask again too..
        cin >> choice;
    }

    //when user presses something but y the loop will exit and come here
    //more useless stuff
    //c=c;
    //b=b;
    cout << "That's too bad. " << endl;	
    system("pause");
    return 0;
