    Unhappy array of vectors

    I need to make a function to initalize the diagonals of an array of 10 vectors to any one floating point number passed as a parameter. The part that I'm unsure of is to initalize the diagonals, how would this be done?
    Thanks

    One solution is a loop. Given there is a 10x10 matrix, here is one solution.

    Code:
    int nCol = 0;
    
    // Top left to lower right
    for (int i = 0; i < 10; ++i)
       array[i][i + nCol++];
