Question

A corporation has six divisions, each responsible for sales to different geographic locations. Design a DivSales class that keeps sales data for a division, with the following members:

• An array with four elements for holding four quarters of sales figures for the division.
• A private static variable for holding the total corporate sales for all divisions for the entire year.
• A member function that takes four arguments, each assumed to be the sales for a quarter. The value of the arguments should be copied into the array that holds the sales data. The total of the four arguments should be added to the static variable that holds the total yearly corporate sales.
• A function that takes an integer argument within the range of 0-3. The argument is to be used as a subscript into the division quarterly sales array. The function should return the value of the array element with that subscript.

Write a program that creates an array of six DivSales objects. The program should ask the user to enter the sales for four quarters for each division. After the data are entered, the program should display a table showing the division sales for each quarter. The program should then display the total corporate sales for the year.

Be sure to create three separate files: the specification file, the implementation file, and the driver program. Use the naming conventions discussed in class.

Input Validation: Only accept positive values for quarterly sales figures.

Explanation / Answer

#include <iostream>

using namespace std;

class DivSales

{

public:

int quarterSales[4];

static int totalSales;

void add(int s1,int s2,int s3,int s4)

{

quarterSales[0]=s1;

quarterSales[1]=s2;

quarterSales[2]=s3;

quarterSales[3]=s4;

totalSales=totalSales+s1+s2+s3+s4;

}

int Sales(int n)

{

int value=quarterSales[n];

return value;

}

};

int DivSales::totalSales=0;

int main()

{

DivSales ds[6];

int i,j;

for(i=0;i<6;i++)

{

int s1,s2,s3,s4;

cout<<"Enter Sales of Division: "<<i+1<<endl;

cout<<"Enter Q1 Sales: ";

cin>>s1;

cout<<"Enter Q2 Sales: ";

cin>>s2;

cout<<"Enter Q3 Sales: ";

cin>>s3;

cout<<"Enter Q4 Sales: ";

cin>>s4;

ds[i].add(s1,s2,s3,s4);

}

cout<<"--------------------------------- ";

cout<<" "<<"Q1"<<" "<<"Q2"<<" "<<"Q3"<<" "<<"Q4"<<endl;

for(i=0;i<6;i++)

{

cout<<"Div "<<i+1;

for(j=0;j<4;j++)

cout<<" "<<ds[i].Sales(j);

cout<<endl;

}

cout<<"--------------------------------- ";

cout<<" Total All Division Sales for the Year: "<<ds[0].totalSales;

system("pause");

}
