how do I input a random number of items as Item ID (string) where a blank item ID signifies the last item?

I want to input an unknown number of variables as Item ID which is a string and when the user enters a blank item, the program should know it is the last input.

>Solution :

This is pseudocode, but you can do it like this:

list = new listOf(string)
input = string.empty

do
    input = readInputFromConsole()
    if not isBlank(input) then
        list.add(input)
    end if    
while not isBlank(input)

Resources:

• List<T>
• Console.ReadLine
• string.IsNullOrEmpty
• The do statement
• The if statement
