    Hi! I'm lost. I'm trieng to write the program. It just won't work. I posted the code below.
    Code:
    #include <iostream>
    using namespace std;
    int main ()
    {
        const int NrOfShops = 3;
        float price;
        char sweets, userAnswer;
        bool answer;
        
    // declare and initialize totals
    float totChoc = 0,0, totChips = 0.0, totIce = 0.0, totOther = 0.0 totSweets = 0.0;
    // loop over the number of shops
    for (int i = 1; i <= 3; i++)
    {
        answer = true;
        cout << "Enter the sweets boaught at Shop nr: " << i << endl;
        
    // sentinel while loop prompting for kind of sweets bought
    while (i <= 3 && sweets == 0)
            {
             cout << "c=chocolate, h = chips, i = ice-cream, o = other and 0 to end: and price: " << endl;
             cin >> sweets, price;
            }
    // enter the kind of sweets bought (c=chocolate,
    // ch = chips, i = ice-cream, o = other) as well as price
    // Update the total cost per kind of sweet
                    switch (userAnswer)
                    {
                     case 'c':
                          (userAnswer++) * price;
                          
                          break;  
                     case 'h':
                          (userAnswer++) * price;
                          break;
                     case 'i':
                          (userAnswer++) * price;
                          break;
                     case 'o':
                          (userAnswer++) * price;
                          break;
                    }
    }
    // display total spent for each kind of sweet
    // update total spent on all sweets so far
    // reset totals of sweets
    // display total spent on sweets at all shops
    system ("pause");
    return 0;
    }
    I hope the comments will help you to understand what I'm attempting to do. I't is just not working and I don't know how to fix it. Any assistance will be welcome!

    Thank you
    Mollera

    Code:
    #include <iostream>
    using namespace std;
    int main (){
        const int NrOfShops = 3;
        float price;
        char sweets;
    // declare and initialize totals
    
    float totChoc[NrOfShops] ={0}, totChips[NrOfShops] ={0}, totIce[NrOfShops] ={0}, totOther[NrOfShops] ={0}, totSweets=0;
    // loop over the number of shops
    for (int i = 0; i <NrOfShops; i++){
        sweets='1';
        //answer = true;
        cout << "Enter the sweets bought at Shop nr: " << (i+1) << endl; 
    // sentinel while loop prompting for kind of sweets bought
    // enter the kind of sweets bought (c=chocolate,
    // ch = chips, i = ice-cream, o = other) as well as price
        while (sweets != '0'){
              cout << "c=chocolate, h = chips, i = ice-cream, o = other and 0 to end:";
              cin >> sweets;
              getchar();
              if (sweets!='0'){
                    cout << "money paid: ";
                    cin >> price;
                    getchar();
                    switch (sweets){// Update the total cost per kind of sweet
                        case 'c':
                          totChoc[i]+=price;
                          totSweets+=price;
                          break;
