Hello everyone. I have a assignment need to be done with using STDC++ library in linux.
I don't know what is STDC++ . And I don't know where to start ? Is if different from C++ ?

Can you tell me sth about StdC++ library , and please demo a simple Program using StdC++ to me.!!!!

Many thanks

libstdc++ is the basic gcc C++ library set (like the C++ equivlent to glibc).

The documentation can be found here:
http://gcc.gnu.org/onlinedocs/libstd...mentation.html

STD C++ is just C++ using standard libraries. If the header file is in your include directory such as /usr/include/c++/3.3.1 this it is part of srd C++. Example header files would be:
ctime.h
iostream
iofstream
cstdlib

Basically if this is for school, the teacher/professor doesn't want to to get on the internet and download a library that does everything for you. Sort of like in math class when you aren't allow to use a calculator.

Here is an example program:

#include <iostream>

using namespace std;

int main()
{
cout << "hello world!" << endl;
return true;
}

I have a problem as following :

Write a program in Linux , using StdC++ library to add ,subtract , multiply , divide two polynomials . The polynomials must be implemented using Pointer or sth like that.

I have no Idea about what to do , could you help me , give me some code

are all the header file in /usr/include/3.3.1 part of STD C++ ?

No. Only the libraries discussed in the documentation I linked to above are apart of the libstdc++ library.

I think these are all the standard C++ libraries
<algorithm>
<bitset>
<deque>
<exception>
<fstream>
<functional>
<iomanip>
<ios>
<iosfwd>
<iostream>
<istream>
<iterator>
<limits>
<list>
<locale>
<map>
<memory>
<new>
<numeric>
<ostream>
<queue>
<set>
<sstream>
<stack>
<stdexcept>
<streambuf>
<string>
<typeinfo>
<utility>
<valarray>
<vector>

These are all the C libraries also included in libstdc++ (notice how they look like the c libraries but have an add c at the front).

<cassert>
<cctype>
<cerrno>
<cfloat>
<ciso646>
<climits>
<clocale>
<cmath>
<csetjmp>
<csignal>
<cstdarg>
<cstddef>
<cstdio>
<cstdlib>
<cstring>
<ctime>
<cwchar>
<cwtype>

This, in reality, is a lot of libraries and a lot of functionality you just don't need for your assignment. What you will need looks like <iostream> (input/output of your data) and that is about it. The math you need is simple so there is no need to use the cmath library. Given this is a school assignment, I doubt you are going to get anyone to actually write any code for you. If you are still completely lost I recommend consulting the class textbook or perhaps your teacher.

Also note.. if you are used to C programming, that there are no .h's. The use of .h in an include is depreciated in newer versions of G++.

Please demo juct add funtion to me . The time is coming up.

Hmm... so you're saying you want us to do your homework assignment for you?

That's a big no.

You won't learn much that way.

My advice, read a C++ tutorial, (like on cplusplus.com, for example... here, I'll make it easy for you, since you're obviously into doing things the easy way and having others do your work for you... click here, you lazy weasel)

Next, go to some place like The Wikipedia and look up with a polynomial is... I don't expect you to know what one is as others have obviously done all of your work for you your entire academic life.

That's it. No more freebies. You should get your ass kicked for publicly trawling for free homework answers... I don't like physically weak people, and I have no respect for the mentally weak, either... most decent programmers don't have time for it, either, as they have all put in time learning everything for themselves, whether in class or on their own.

Its not that hard.
