Assume I have a function:
void isUniqueSymbols(string stream)
How to understand that I should provide several examples of how my function works?
I can write something like this:
Input: isUniqueSymbols("abcde");
Output: true;
Input: isUniqueSymbols("abcdee");
Output: false;
But not sure this is correct.
How would you provide examples of working function?
One possibility would be the embed the documentation into code:
assert(isUniqueSymbols("abcde"));
assert(!isUniqueSymbols("abcdee"));
This is pretty close to unit testing/viewing unit tests as documentation, for whatever that may be worth.

My C++ program needs to take in two arguments text or calc, those are the two functions,
How do I set this up to read in 2 input files using a map?
You need to pass command line arguments. You can find plenty or resources online. Here are a couple of examples: http://www.cplusplus.com/forum/articles/13355/ and http://msdn.microsoft.com/en-us/library/17w5ykft.aspx.

I would rather suggest you to get an introductory C++ book from this list and read it properly :
The Definitive C++ Book Guide and List
Then you'll know what you're asking. You need to study a book first, before asking such questions!

As you know, C++ allows multiple inheritance. But, would it be a good programming approach to use multiple inheritance or it should be avoided?
Thanks.
In general, it's not needed and can make your code more complex.
But there are cases where it's useful. As long as it's useful and isn't causing your code to become unmanageable, I see no reason to avoid it.

Before I knew that C was faster than C++ I was able to write some simple code where C executed faster than C++'s speed.
So my question is: please explain then reason behind this.
If this has already been explained elsewhere on this site or the internet, please share a link.
The reason behind this is your poor test.
C is not faster than C++ because C++
is a superset of C.
Here it is!

i don't know what the remote_api will do
thanks
You can read about remote_api here: http://code.google.com/appengine/articles/remote_api.html
At a high level, it allows you to write code which interacts with your appengine application code and datastore without having to go through the request/response model.
