More c++ problems

Hey guys, thanks foor the help in the other thread really helped me out alot. Here is some more problems I am stuck on. Thanks.

Code the following functions in C++ that determine whether a given string, representing an input
line, is blank.
1. f1: based on iteration across the string using the indexing operator
2. f2: based on iteration across the string using an iterator
3. f3: based on the use of a predicate and an appropriate generic library function to perform the necessary iteration. Explain why the predicate is necessary.
4. f4: based on the use of a functor (function object) and an appropriate standard library function to perform the necessary iteration.

Let's see your work before we give any hints about it. You won't learn anything by us doing your homework for you.
