Please Guys, I need your help. I don't understand were to start in writing a program to solve the problem below. I saw this question on my C++ How to program Textbook by DEITEL AND ASSOCIATE. Please i don't need the actual C++ code. All i need is the pseudo-code or some kind of explanation to aim my understanding of the concept. I will appreciate any effort regarding this correspondence. THANKS.

/*
(Sales Summary) Use a two-dimensional array to solve the following problem. A company
has four salespeople (1 to 4) who sell five different products (1 to 5). Once a day, each salesperson
passes in a slip for each different type of product sold. Each slip contains the following:
a) The salesperson number
b) The product number
c) The total dollar value of that product sold that day
Thus, each salesperson passes in between 0 and 5 sales slips per day. Assume that the information
from all of the slips for last month is available. Write a program that will read all this information
for last month’s sales (one salesperson’s data at a time) and summarize the total sales by salesperson
by product. All totals should be stored in the two-dimensional array sales. After processing all the
information for last month, print the results in tabular format with each of the columns representing
a particular salesperson and each of the rows representing a particular product. Cross total each
row to get the total sales of each product for last month; cross total each column to get the total
sales by salesperson for last month. Your tabular printout should include

Since I don't know how much you know, I guess it's safe to show how I'd do it using a struct to hold:

a) The salesperson number
b) The product number
c) The total dollar value of that product sold that day[/quote

And a multidimensional array to hold:

A sample of the array would be:
slips DailySlips[4][5];

And then this part:

Looks to ask you to read in from an imaginary file (maybe create one yourself) and analyze the results

And then here:

All totals should be stored in the two-dimensional array sales. After processing all the
information for last month, print the results in tabular format with each of the columns representing
a particular salesperson and each of the rows representing a particular product. Cross total each
row to get the total sales of each product for last month; cross total each column to get the total
sales by salesperson for last month. Your tabular printout should include

It looks like it's just asking you to get a total of each persons total amount of slips and sales, which would just simply be a running tally.

A sample of your file might look like:

387264
FS470
500.00

The first being the salesperson's number, second being product number, third being total sales in dollars.
