To print the last element of a list in Haskell, you can use the last function provided by the standard library. You simply pass the list as an argument to last and it will return the last element of the list. You can then print this value using the print function. Here is a basic example:
1 2 3 4 |
main = do let myList = [1, 2, 3, 4, 5] let lastElement = last myList print lastElement |
In this example, myList is a list containing integers and we use the last function to retrieve the last element of the list and store it in the variable lastElement. Finally, we print the last element using the print function.

What function should I use to print the last element of a list in Haskell?
You can use the last function in Haskell to get the last element of a list.
For example, if you have a list [1, 2, 3, 4, 5], you can use the following code to print the last element:
1 2 3 |
main = do let myList = [1, 2, 3, 4, 5] print (last myList) |
This will output:
1
|
5
|
What is the quickest way to retrieve the last element of a list in Haskell?
To retrieve the last element of a list in Haskell, you can use the last function which takes a list as input and returns its last element.
For example, if you have a list called myList and you want to retrieve its last element, you can do the following:
1 2 |
myList = [1, 2, 3, 4, 5] lastElement = last myList |
In this case, lastElement will be equal to 5, which is the last element of the list myList.
How to access the final item in a Haskell list?
To access the final item in a Haskell list, you can use the last function which returns the last element of a non-empty list. Here is an example:
1 2 |
lastItem :: [a] -> a lastItem xs = last xs |
You can then call this function with a list to get the final item:
1 2 |
myList = [1, 2, 3, 4, 5] finalItem = lastItem myList |
In this example, finalItem will be equal to 5, which is the final item in the list myList.
