    STL vector<float> vecs, multidimensional

    Hi there,
    I'm new to C/C++ and need some help. under www.cppreference.com in the STL there is a Template of vector to make vectors. How can i make this Vector multidimensional?
    My target is a 2dimensional array, which contains a list of vectors.
    I have a file with 3 floats in a row, which needs to be written in a multidimensional array.
    Coords x y z
    in
    vecs[num][x]
    vecs[num][y]
    vecs[num][z]

    Thanks in advance!

    You mean you can't/aren't going to just create a struct that contains the three points and use that struct as the type for the vector object?
    Code:
    struct coord
    {
        float x;
        float y;
        float z;
    };
    
    vector<coord> CoordVector;
    Doesn't seem to me that you really need to make this a multidimensional vector. Are there design considerations/requirements here that are pushing you towards this decision?
