Question

Need help with this programming please this is the instruction my teacher provided

Write a C++ class called "Sales" and a main( ) function that uses the class. Also, write documentation of your project. Below is a specification of the class. . INTRODUCTION A company has four salespeople (1 to 4) who sell five different products ( to 5)1. Once a day each salesperson passes in a slip for each different type of product sold. Each slip contains: The salesperson number The product number Date of sale The total dollar value of that product sold that day Thus a salesperson passes in between 0 and 5 slips per day Here is an example of daily sales data: PRODUCT ID AMOUNT 127.57 3123.99 47.77 500.00 268.72 SALESPERSON ID 894.50 2. DATA STRUCTURES First, provide a struct of the sales slip. Second, provide the class whose data members are as follows: A one-dimensional array of slip structures to be used to store sales information for all the sales people for a month. A two dimensional array that wil array where the rows shall represent salesperson and the columns shall represent product. A one-dimensional A one dimensional array of product names. l contain a summary of the data from the one dimensional ional array of names of the four salespersons. 3. PROGRAM LOGIC 3.1 Input A function member of the class to input data into the one-dimensional array from the keyboard.

#include <iostream>
#include <algorithm>
using namespace std;

double total = 0;
double grandtotal = 0;
  
public:
//member function to get sales slips
void inputSales(void);
//member function to print sales summary

//member function definition, outside of the class

}

//member function definition, outside of the class

for (int k = 1; k <= 4; k++) {

cout << "\n";
}

if (summary[k][1] == summary[k-1][1]){

cout << "\n";
cout << "\n GRAND TOTAL OF ALL SALES : " << "\t\t\t\t" << grandtotal;
}

int main()

for (int i = 0; i <= 4; i++){
std.inputSales();
std.computeTotal(i);
}
std.outputTable();

return 0;
