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:

  • declare an integer x
  • input x
  • add If block with value x > 0
  • in the true branch output "Positive"
  • in the 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.
