Answer 1

#include <iostream>
 
#define ROWS 3
#define COLS 4
 
void printMatrixCorners(int matrix[][COLS], int rows, int cols)  {
    std::cout << "left top corner: " << matrix[0][0];
    std::cout << "\nright top corner: " << matrix[0][cols - 1];
    std::cout << "\nleft bottom corner: " << matrix[rows - 1][0];
    std::cout << "\nright bottom corner: " << matrix[rows - 1][cols - 1];
}
 
int main()
{
    int matrix[ROWS][COLS] = {
        { 1, 2, 3, 4 },
        { 5, 6, 7, 8 },
        { 9, 3, 2, 0 }
    };
 
    printMatrixCorners(matrix, ROWS, COLS);
}
 
 
 
/*
run:
 
left top corner: 1
right top corner: 4
left bottom corner: 9
right bottom corner: 0
 
*/
