  9. Write a program that sets up a 10 x 12 two-dimensional array of integers - i.e. a matrix of 10 rows, 12 columns.
    a) Populate every element of the matrix with a random number between 1 and 1000;
    b) Print out the array as 10 rows x 12 columns (remember the setw() manipulator, which requires the <iomanip> library to be included).

  10. Re-write exercise 9 using two functions, populate and print, whose parameters are the matrix, and the number of rows.
