How to print a String and then call the same function in the same guard-CodePudding

So I am making a function that I want to call, print a string depending on the value (with guards), and then call that same function again with different values.

This is what I was thinking

something a
| a <= 1 = "One" && (something (a 1))
| a == 2 = "Two" && something (a 1)
| a >= 3 = "Three" && something (a 1)
| otherwise = something a

I know this is an endless loop and I know this is wrong but it's just the idea I had.

Any idea to make this would be appreciated.

CodePudding user response：

You should change the "&&" , instead use the " ". Try this:

something :: Integer -> String
something a | a <= 1 = "One"    something (a 1)
            | a == 2 = "Two"    something (a 1)
            | a >= 3 = "Three"    something (a 1)
            | otherwise = something a

main = do 
   putStrLn "Result:"  
   print (something 1)
