string question

this is the c++ question i have...any help on the function...

Ques. Write a function to delete all trailing spaces(spaces at the end)from a string supplied as input via a parameter.
Indicate two different ways of returning the result.

any help wud be helpful..

This looks rather like an assignment to me. Have a go yourself then ask when you get stuck rather than trying to get someone else to do it for you. Having an end result is no use in learning to program, what you need is the experience of getting there.
