Inputs

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


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

  • declare an integer x
  • add x block, with variable name x
  • output x * 2

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