Sounds like you need to learn the basics of C++. Here, http://www.cplusplus.com/doc/tutorial/ , a tutorial in this site just for what you need.

If you come across something you don't really understand, just ask the question.

i done this coding.. but still cant run.... can you check this coding and give me a solution...

[webJose]

I will surely check it out once you put it inside code tags. :D

http://cplusplus.com/articles/z13hAqkS/

That should explain how to use them. It's just that I read formatted code everyday, and unformatted code is just so hard to read.

You pass C arrays as parameters?
If you try to write data in forbidden memory your program will crash.
Since you're a C++ programmer, you should learn to use what C++ provides.

Example:

#include <deque>

std::deque<int> read_colors()
{
    std::deque<int> colors;
    int user_color = 0;

    // read user_color int's from user
    // while (...) {
    colors.push_back(user_color);
    // }

    return colors;
}

int main()
{
// ...
std::deque<int> C = read_colors();
// ...
}
