Question

In C++.

Write another program in file B2.cpp to calculate and print the total sales of each product by each salesperson. Read the sales slips from the file Salesslips.txt (or for partial points, in case your program Bl.cpp does not work correctly, from an array with the same data, initialized in your main program) and calculate the total sales of each product by each salesperson. Accumulate the total sales of each product by each salesperson in a two- dimensional array with a row for each salesperson and a column for each product. You may use the salesperson's ID number from the following table as a row number for the corresponding salesperson. Salesperson's ID number Bill Name ܢܕ Eric 2 3 Sookie Tara 4

Answer 1

Code is as follows:

******************************************************************************************************************************

#include <iostream>
#include<iomanip>
#include<fstream>
using namespace std;

int main()
{
double sales[4][5] = {0}; //declare and initialise to all zeroes
  
ifstream infile; //ifstream object
infile.open("SalesSlips.txt"); //opne the file
  
//variables for input from file
string name;
int product;
double amount;
  
//read every line and extract name product and amount
while(infile>>name>>product>>amount){
  
int id; //check name and assign id
if(name=="Bill"){
id = 1;
}
else if(name=="Eric"){
id = 2;
}
else if(name=="Sookie"){
id = 3;
}
else{
id = 4;
}
//take switch case and put in respective cell of the 2d array
switch(product){
case 1:
sales[id-1][0]+=amount;
break;
case 2:
sales[id-1][1]+=amount;
break;
case 3:
sales[id-1][2]+=amount;
break;
case 4:
sales[id-1][3]+=amount;
break;
case 5:
sales[id-1][4]+=amount;
break;
}
}
  
//print to the console
cout<<left<<setw(9)<<"Product #";
printf("%7d",1);
for(int i=1;i<5;i++){
printf("%10d",i+1); //every Product number
}
cout<<endl;
for(int i=0;i<4;i++){
string name;
if(i==0){
name="Bill";
}
else if(i==1){
name="Eric";
}
else if(i==2){
name="Sookie";
}
else{
name="Tara";
}
cout<<left<<setw(9)<<name; //name of the person
for(int j=0;j<5;j++){
printf("%10.2f",sales[i][j]); //sale of that person
}
cout<<endl;
}
return 0;
}
