If-s

We already saw that a program executes one command after another, from top to bottom. But usually we need some branching/decisions to make while executing a program. Let's write a program that will print if a number is positive or negative:

For example, if user enters number 9, output should be "Positive". If user enters number -55, output should be "Negative".

Maybe you haven't thought about it, but expression x > 0 has type Boolean. Boolean can be true or false.
