How to pass 2D array (matrix) in a function in C?

Question

I need to do this to persist operations on the matrix as well. Does that mean that it needs to be passed by reference?

Will this suffice?

void operate

     #include 
     using namespace std;

     void printarray(int *a, int c,int r)
     {
        for (int i = 0; i < r; i++)
        {
            for (int j = 0; j < c; j++)
            {
                cout << "\t" << *(a + i*c + j) << "\t";  // a is a pointer refer to a 2D array
            }
        cout << endl << "\n\n";
        }
     }

     int main()
     {
         int array[4][4] = 
         {{1 ,2 ,3 ,4 },
          {12,13,14,5 },
          {11,16,15,6 },
          {10,9 ,8 ,7 }};

          printarray((int*)array,4,4);
          // here I use print function but u can use any other useful function like 
          //setArray((int *) array,4,4);

        return 0;
    }
