ok i got a new project from my teach where i have to make a guessing game for example choose a number between 1 and 10 you have 2 guesses how would i make this?? my teacher said i needed for loops?? help XD and also where i enter a number and i give the computer an amount of guesses to guess and then he gueeses the number i entered... Both ways NEEDED!

Re: loops?

well.. for them to choose the number, the normal code would be something like this :

Turing:

var number : int

loop
put "Choose a number between 1 and 10"
get number
exit when number >= 1 and number <= 10
end loop

Now, to make the guesses.. what you have to do is have a counter variable (starting at 0) that records the number of tries.
In the loop statement, you have to check if the number of tries is either 0, 1, or 2. Then, you have to make the condition (in the loop itself) to exit the loop when either
the number of tries is 2 OR the user has guessed the number. I realize, however that you have to do it with for loops.

Well, to do the same thing above, the for loop version would be

Turing:

var number : int
var number_of_tries := 2

for i : 1 .. number_of_tries
put "Choose a number between 1 and 10"
get number
exit when number >= 1 and number <= 10
end for

All you have to do is to make it so that when the user guesses a number, to have a randomized number inbetween 1 and 10 and check if it's the same or not.

one suggestion is try first, the way you think it should be done, THEN ask for help.

Yea thats good. thanx but now i gotta think of like how to assign a number and is ther a way for the comp to choose a random number i need to gueess it?

Re: loops?

here it is

Turing:

%Brandon
%Guess
%October 19 2009
%-----------------------------------------------------------------
var number :=7
var numguess : int
var guess : int
locate (1, 30)
put "Guessing Game"
put "The objective of the game to to guess the correct number."
put "please guess the number. "
get number
if number = 7 then
put "Correct"
else
put "Wrong"
end if

but the way i did it is u need to choose 7 and i want the comp to choose a number for me then i try to figure it out

I still need to make another game but i choose a number and computer gueeses what the number is
and here is sumthing i quickly made but then agen the answer is always 7 and i want the comp to generate 1

Turing:

var number : int
var numguess : int
loop
put "Choose a number between 1 and 10"
get number
if number = 7 then
put "You win "
exit when number >= 1 and number <= 10
put "try again"
end if
end loop

look into the docs and find Math.Rand() that will allow the computer to generate a pseudo-random number. Also, your loop is useless since your exit condition uses the wrong range. it does, however, exit your if statement if the number is in that range, but it should exit either when the user chooses the correct value, not when they choose incorrectly since at the moment , the "try again" message never gets displayed. I think you meant to use an else there, and move the exit condition outside your if statement.

look into the Randint() function... it generates a random number from a range that you can assign.

Re: loops?

ok after a long period of time i cam up with this

Turing:

%Guessing Game
%________________________________________________________________________________________
var number : int
var number_of_tries : int
var easy : string
var medium : string
var hard : string

%___________________________________________________________________________________
locate (17, 25)
put "How many guesses do you want?"
get number_of_tries
for i : 1 .. number_of_tries
put "Choose a number between 1 and 50"
get number
if number < 47 then
put "Higher"
else
put "lower"
if number = 47 then
put "you got it!"
exit when number >= 1 and number <= 50
put "You win "
end if
end if
end for

if all thos put statements look weird then jus backspace it but it says Guessnig Game

tell me what you think
now i want to chalenge myself and make level 1-3 what i mean is like modes so easy, medium and hard my only idea is to make the variables and with and if statement
for ex.

Turing:

var easy : string
var medium : string
var hard : string
var answer : string

locate (1, 30)
put "Choose you game mode"
get answer
if answer = "easy" then
put "You chose easy. "
else
if answer = "medium" then
put "You chose medium"
else
if answer = "hard" then
put "You chose hard."
end if
end if
end if

now i just need to link it all XD i tried but keep getting errors, im newbi! Mr. Green

Re: loops?

after i get the 3 stages i need the answer to be generated and i also wanna kno if its possible to have the Higher and lower thing if its a random number

Rand.Int() is the function you're looking for to generate the random number to be guessed. You're on the right track for the rest of it.
