    Question vector<...>.....What is it?

    I have seen stuff like this:


    and stuff like that. What is it and what does it do. I know a lot of C++ and I have some experience w/ OpenGL and SDL, but I never used this stuff before. Any answers?


    C++ Environment: MSVC++ 6.0; Dev-C++ 4.0/4.1

    No you don't, try a decent C++ book. std::vector is part of the C++ standard template library, and is intended to replace the need to hand code an efficient generic dynamic array.

    That is a vector class that uses templates. The templates allow the vector to be of any data type. You can look up info about the STL on As well you can d/l the current version of the STL from that site.

    the stl is newer (i think) than a lot of c++

    anyway... here's an example:
    PHP Code:
    vector<vector <int> > array; // array of array of ints
    vector <intx;
    x.push_back(5); //x[0]=3, x[1]=5
    push_back(x); //neat, huh? 
    that's a small segment. the stl can sort it, swap two values, reverse (i think), and may other things. all of the above can be done on the whole list or just a small section

    As with what ygf showed, a vector < vector <int> > can be made into a non-square matrix.
