Module main()
      Declare Integer number
      Display "Enter a number and I will display"
      Input number

      Display number
 End Module

Module doubleNumber(Integer value)
     Declare Integer result
     Set result = value * 2
     Display result
End Module

Answer 1

The code will ask the user to enter a number(here lets say 4 is entered) Then a doubleNumber function will be called which will set the result variable to number * 2 (here it will be 8) and display it. After that in original function the input number will be displayed.

Note: HERE taking 4 as a input number.

The output of the following code will as follows:

1. Enter a number and I will display
2. 8
3. 4
