You would either need to put your switch statement inside the loop used to take the user's order, or you would need to create an array to keep track of what they ordered and how much of it and checking to see if they ordered something before outputting it to the screen.

Your program currently is fundamentally broken because your switch statement after the loop only checks the last choice the user made.

How can I differentiate each choice?
for example, if I buy coffee and scone, how can I cout "you have bought coffee and scone"?

[TheKingOfTyrants]

Your program currently has two arrays: one with the price of items, one with the name of items. You'd only need to create one more to keep track of how much of each item a user ordered. Then you would use a for statement to iterate through all items, and if they quantity purchased is greater than zero, you would output to screen.

Can you give me an example or elaborate? I am new to C++, I dont know how that would work. Also, the sample is supposed to run like this :

I'm pretty much saying you need a counter variable. If the counter for an item is greater than zero, then that should be a condition to output that item to the screen.

int main (void)
{
    int choice;
    int bag_of_numbers[10] = {0};
    while (true)
    {
        cout << "Pick a number to add to the bag: ";
        cin >> choice;

        if (choice < 1 || choice > 10 )
            break;

        ++bag_of_numbers[choice - 1];
    }

    cout << "The numbers you chose: " << endl;
    for (int i = 0; i < 10; i++)
    {
        //check to see if numbers are in the bag. Only then will I output.
        if ( bag_of_numbers[i] > 0 )
            cout << "The number " << i + 1 << " is in the bag " << bag_of_numbers[i] << " times." << endl;
    }
}
