Does that seem viable?

Uh, I don't think you've understood this.
If you generate a random number from 1 to 3, then there is an equal chance of each number coming up. For instance, there is a 33% chance that the function will return 1. However, there is a 67% chance that the generator will return either 1
or 2. By using a
range of numbers, you can generate different probabilities.
Now, reread my earlier statement: Consider a random number generator that generates a number from 1 to 100. There will be a 20% chance the random number will be
between 1 and 20.
Do you understand now?

You will have no doubt looked up the factory design pattern, and thus you will no doubt know that a factory class is designed to create objects. A CustomerFactory will produce Customer objects.

I'd use a vector myself, or some other similar data structure. Are you allowed to use the C++ STL?
In any case, either you use a sorting algorithm in the language, or you build one yourself. Have you covered quicksorts or bubblesorts?

Yes... But only for statistical purposes.

Think of it this way. You have a loop, where each iteration represents one second, and at the end of the loop, a counter is incremented. You query each customer with the current "time", and you discover one who is scheduled to enter the store. It gets placed in line, and you tell it to start paying. Every iteration of the loop you ask it if it has stopped paying, and if it says yes, you remove it from the store. If a customer comes in whilst another is waiting, you place it in the queue.

The STL is a good bet, but queues are data structures that operate on a FIFO basis (first in, first out). You want a class that delivers customers in alphabetical order.
