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.
