    double matrix and data structure?

    a program that stores and processes sparse matrices of floating point numbers. The matrices are of a fixed xize(1,000x1,000 elements), but only a small percentage of the elements have non-zero values. Suggest a method for storing the matrices that is more economical with memory than a two-dimensional array of 1,000x1,000 floats. Write C definitions for your suggested data structure(s).

    I use linkedlist to do it.

    struct matrix {
    int row;
    int coloum;
    struct node *next;

    } node;

    is it right? then how to do it?

    In the absense of more information, its as good as any other method.

    There are no correct answers - any number of solutions are possible. All will have advantages and disadvantages, and as you gain experience, you will be able to make better choices.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
