Inputs

In previous examples we used fixed (hardcoded) values in programs.
But sometimes we need a value as an input from the user. When a value gets read from the user, FlowRun stores it in a variable.

Let's write a program that reads a number from the user and outputs its value doubled:

• declare x: Integer
• add an Input block, with variable name x (x)
• output x * 2

For example, if the user enters 9, output should be 18.
