Randomize Procedures

Is there a way for me to randomize a set of procedures? Say 1 procedure is asking 1 question and it also includes the correct answer, but there are 40 procedures and i wanna take out 20 random ones. Can anyone please help me?

Sure, you can make an array of procedures and then pick a random element. Or you could have all your questions and answers stored in a file, then read the data into an array so that you've got one element for each question, then pick a random element. I think the second approach is better, because it involves a more general solution. You don't have to write a new procedure for each question. Your code will stay small, even if you have thousands of questions.

oh and also i tried to make an array of procedures

like
procedure question1
bl bla bla
end question1
procedure question2
bla bla bla
end question2

var randomquestion :array 1..2 of int
var num : int
randomquestion (1) := question1
randomquestion (2) := question2

loop
num := Rand.Int (1,2)
put randquestion (num)
end loop

but it gave me an error:

"Assigned"

Try This:
Turing:
proc p1
    put "Procedure 1"
end p1

proc p2
    put "Procedure 2"
end p2

proc p3
    put "Procedure 3"
end p3


var p : array 1 .. 3 of procedure blah ()


p (1) := p1
p (2) := p2
p (3) := p3


p (Rand.Int (1, 3))

Yeah, procedures are not integers. Wink

The thing is that a procedure that accepts no arguments is different from a procedure that accepts one argument, and that is also different from a procedure that accepts two arguments, etc. Probably the way to go with this approach is to make all your procedures accept no arguments.
