Re: [Haskell-cafe] Change value of a variable

What i am exactly to do is this: I have a list of pupils (type Pupil = (Name, Grade)) where I store the name of the pupil and which grade he has. No I want to get the number (and average number) of each grade. Something like 10 Pupils have a A (23%), 2 Pupils have a B ( 4 %) etc -- View this message in context: http://www.nabble.com/Change-value-of-a-variable-tp23913404p23914558.html Sent from the Haskell - Haskell-Cafe mailing list archive at Nabble.com.
