Write a C++ program that declares the following 2 arrays: const int Rs = 8, Cs = 8; double arr[Rs][Cs]; double arr_quarter[Rs / 4][Cs / 4]; //fill in the array with some data for (int r = 0; r < Rs; r++) for (int c = 0; c < Cs; c++) arr[r][c] = r * 8 + c;

Write a C++ program that declares the following 2 arrays:
const int Rs = 8, Cs = 8;
double arr[Rs][Cs];
double arr_quarter[Rs / 4][Cs / 4];
//fill in the array with some data
for (int r = 0; r < Rs; r++)
for (int c = 0; c < Cs; c++)
arr[r][c] = r * 8 + c;
Then:
- Print out the diagonal of arr
- Print out the anti-diagonal of arr
- Downsize arr by a factor of 4 (i.e. Rs/4 and Cs/4) and store the result in arr_quarter. Then print it out.
- Then upsize arr_quarter by a factor of four and store the result in arr and print it out.
Expected output:
