write 2 programs:
One program will use a structure to store the following data on a company division:
Division Name (such as East, West, North, or South)
Quarter (1, 2, 3, or 4)
Quarterly Sales
The user should be asked for the four quarters' sales figures for the East, West, North, and South
divisions. The data for each quarter for each division should be written to a file.
The second program will read the data written by the first program. The program should
calculate and display the following figures:
Total corporate sales for each quarter
Total yearly sales for each division
Total yearly corporate sales
Average quarterly sales for the divisions
The highest and lowest quarters for the corporation
Input Validation: Do not accept negative numbers for any sales figures
