If at all you want to throw string literals, remember that they are const char* not simply char*. So refactor your code as:

Uh good. But I think you realised your limitation.
For sorting integers, there are many algorithm available (http://en.wikipedia.org/wiki/Sorting_algorithm#Summaries_of_popular_sorting_algorithms)....

stringstreams (http://www.cplusplus.com/reference/iostream/stringstream/) are often useful when you want to parse a sting input, specially when you need to do something with words.

Looks like you are trying to loop some statements. But the syntax of the loop is not correct. Read http://www.cplusplus.com/doc/tutorial/control/ (Loops) to find out the correct format.

Use a std::map (http://www.cplusplus.com/reference/stl/map/).
Create a map<std::string, int>.
Scan through the file and insert each of the word to the map with initial value 1. If the word already...

Get some sand and clay. Try to first model desks and benches. Then model teacher and students. And your class is ready.

This is called explicit template instantiation.

Is it?
This is the correct way to the thing what you want.
You create a class template when you want to separate the implementation of the whole class according to the template...

Re-factor the simplify function which finally converts a/-b to -a/b. This will maintain uniformity and thus the program will be unambiguous.

Your function will work good for all positive integer but would fail when N=0.

You really need to go down to the basics of inheritance - why we use it.
When you construct a base class, it is not really a base class but it is 'just a class'. It is when you use that class to...

Have a close look on what are you doing.
In the loop at line 12, you read each line in one iteration to the std::string line.
Now you iterate a for loop nested inside the while loop and assign all...
