Need Help adding a counter

Post subject:  Need Help adding a counter
What is it you are trying to achieve?
I created a guessing game and i am having trouble adding a counter in. so that when you guess the right number it will show you how many guess's it took you to get that number


What is the problem you are having?
it puts 0 where i want it to put number of guess it took


Describe what you have tried to solve this problem
i tried adding a var outside of the for loop and declaring it as 0 and making it so it goes up by one everytime the loop is ran.
Post any relevant code (You may choose to attach the file instead of posting the code if it is too long)


Turing:


color (yellow)
colorback (red)
cls
var guess : int
var number := Rand.Int (1, 100)
var num : int
num := 0

for i : 1 .. 100
    put "Choose a number between 1 and 100"
    get guess
    cls
    if guess < number then
        put "Higher"
    elsif guess > number then
        put "lower"
    end if
    if guess = number then
        exit
        num := num + 1
    end if
end for

put "Congratulations you got it right. It took you ", num, " tries."



Please specify what version of Turing you are using
turing 4.1

Your flow of control is very wrong. The code for incrementing your num variable will never be executed because it occurs immediately after an exit, which will take you out of the loop without executing anything further. It also never happens on incorrect guesses.

All I can say is add more comments and make your variables more descriptive so whoever is reading your code will actually want to read it.. as for counter, you use variable += 1 or variable := variable + 1. And you have to put that inside the loop where you have to guess again. So basically what you can do is

code:

loop
    Please enter your guess: " ..
    get guess
    noOfGuesses += 1

why is it in a for loop, it should be in a regular loop, that will also make it easier to add a counter


Turing:
color (yellow)
colorback (red)
cls
var guess : int
var number := Rand.Int (1, 100)
var num : int
num := 0

loop
    put "Choose a number between 1 and 100"
    get guess
    cls
    if guess < number then
        put "Higher"
    elsif guess > number then
        put "lower"
    end if
        exit when guess = number
    num += 1
end loop

put "Congratulations you got it right. It took you ", num, " tries."
