Write a program that lets the user enter four quarterly sales figures for three

Question

Write a program that lets the user enter four quarterly sales figures for three divisions of a company. The figures should be stored in a two-dimensional array. Once the figures are entered, the program should display the following data for each quarter:
• A list of the sales figures by division
• The total sales for the quarter
• The average sales for all divisions that quarter
• The division with the highest sales for that quarter
The program should be modular, with functions that calculate the statistics above. Use the following sales table to test the program
Input Validation: Do not accept negative numbers for sales figures.


SALES:
Quarter 1 Quarter 2 Quarter 3 Quarter 4
Division 1 34 42 22 43
Division 2 33 33 40 28
Division 3 29 27 30 35
