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:
x
x
x > 0
true
branch output "Positive"
false
branch output "Negative"
For example, if the 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
.
