At this point we have 70-294 looked at some of the elements of a programming language like variables, expressions, and statements in isolation, without talking about how to combine them.
One of the most useful 70-431 features of programming languages is their ability to take small building blocks and compose them (solving big problems by taking small steps at a time). For example, we know how to multiply integers and we know how to output values; it turns out we can do both at the same time:
Actually, I shouldn't say "at the same time," since in reality the multiplication has to happen before the 70-536 output, but the point is that any expression, involving numbers, characters, and variables, can be used inside an output statement. We've already seen one example:
