This lab is an exercise with pointer arithmetic. In mathematics, an identity matrix has l's on the main diagonal, where the row and column index are the same, and 0's everywhere else. Each element must be visited to populate the matrix in some systematic fashion. A pair of nested for loops - one that steps through every row index and the nested loop that steps through each column index can be used to accomplish this task. To populate this matrix, every element must be visited #include #include #define N 6 1 2 3 4 5 6 int main() pl double ident [N] [N]; int row, col; 9 10 12 13 14 15 16 17 18 19 20 21 22 23 for (row = 0; row
