C++ 2D array to 1D array

Question

I am attempting to convert a 2D array to 1D. I\'m extremely new to C/C++ but I think it\'s very important to learn how to convert a 2D array to 1D. So here I am stumbling u

Answer 1

You are right with your supposition:

The cycle should be like:

for (q = 0; q < n; q++)
{
    for (t = 0; t < m; t++)
    {
        b[q * m + t] = a[q][t];
    }
}

It is always easier to consider such conversions from the view point of the higher dimension array. Furthermore with your code you did not actually modify i or j in the b assigning cycle, so you should not expect different values to be assigned to the different array members of b.
