• Statements

    A condition statement is like a question in programming. It helps the computer decide what to do next. For example, if you go to a store, you might ask the shopkeeper if they have what you want. The shopkeeper will answer yes or no, and that will help you decide what to do next. In programming, the computer can ask itself questions to decide what it should do next.
