Write a program that defines and initializes the elements of a m x n matrix, a, from the user. then calculate and prints the average for every row and for every column. for example, in the matrix: [5 4 11 21 2-2 12 1 -5 4 -5 0 average for row 0 is 10.25 average for row 1 is 3.25 average for row 2 is -1.5 average for column 0 is 3.7 average for column 1 is -1 average for column 2 is 7.7 average for column 3 is 5 hint: define m and n as cons int, and your program should work for any value of m and n
