Matrix, pointers, C*

Question

I have code like this:

void print_matrix(int **a, int n) {
    int i, j;
    for(i = 0; i < n; i++) {
        for(j = 0; j < n; j++)
            printf(\"%         


        

Answer 1

If you want n to vary (and be square), it is best to allocate and use a single dimension array and multiply when you want a different row.

int matrix[3*3];

How to use it?

matrix[row*3+col] = 5;

How to pass it.

f(int *a,int n)
