I'm relatively new to haskell and have some questions:
1- I want to convert an integer to a char( if I say prelude> convert 4 ... it should return prelude> '4')
2- and vice versa?
Use chr and ord respectively, from the Char module.
3- I want to define a function that stores in a variable the following...
pretended: (Int,Int,Int,Int)
give :: IO Int give = randomRIO (0,9)
main = do k <- (give,give,give,give)
actualy this isn't possible. but can someone please tell how to do this???
main = do
k1 <- give
k2 <- give
k3 <- give
k4 <- give
let k = (k1, k2, k3, k4)
Or:
main = do
[k1, k2, k3, k4] <- sequence $ replicate 4 give
let k = (k1, k2, k3, k4)
