11.1 Question-answer

The program that we’re going to create in this chapter will ask the user his first name, his name and his age. At the end, the program will make a synthesis!

 Your first name is: .......
 Your name is: .......
 Your age is: .......
 You’re over 20/less than 20

HERE ARE THE PRIMITIVES WE’RE GOING TO USE:

• read:      read [ ] "a
  
  Displays a dialog box whose title is the text from the list (here, “How are you?”). The answer given by the user is stored in a word or in a list (in case of several words) in the variable :a.
• make:      make "a 30
  
  Gives the value 30 to the variable :a
• sentence, se:      sentence [30 k] "a
  
  Adds a value in a list. If this value is a list, removes square brackets.

  sentence [30 k] "a ---> [30 k a]  sentence [1 2 3] 4 ---> [1 2 3 4]  sentence [1 2 3] [4 5 6] ---> [1 2 3 4 5 6]

This is the code program:

                                                                                                  
                                                                                                  
 to question
 read [How old are you?] "age
 read [What’s your first name?] "fname
 read [What’s your name?] "name
 print sentence [Your name is: ] :name
 print sentence [Your first name is: ] :fname
 print sentence [Your age is: ] :age
 if or :age>20 :age=20 [print [You’re over 20]] [print [You’re less than 20]]
 end
