    Smile Could somebody help sorting matrix elements in non-decreasing order?

    Dear all,

    I'm a beginner of C programming, and I've asked to sort N x N matrix of integers randomly generated
    in non-decreasing order such like...

    1 5 9 13 25
    2 6 11 16 27
    3 7 14 18 28
    4 8 15 21 30
    10 11 20 23 50

    At the first glance, I thought it's just an extension of sorting algorithms in 1-dimension array, but it becomes rather clear that it's far more than that xD

    I would appreciate if somebody can help me working with this monster...


    Thanks

    Well if you only have to sort within a row (which your example implies), then it really is just a simple sort, repeated for each row of the matrix.
    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.
