Question

Help.

Write a C++ program that determines which of a company's four divisions (North, South, East, West) has the greatest sales for the quarter. It should include three functions at a minimum:

float getSales() is passed the name of a division. It asks the user for a division's quarterly sales figure, calls a validate() function that will validate the input, and then returns the value back to main(). This function should be called once for each division.

void validate() is called from the getSales() function to ensure the input value is not negative nor has character input. If invalid input is found, loop until the user enters a valid value. It will then return to getSales().

void findHighest() is passed the four sales totals. It determines which is the largest value and prints the name of the high grossing division along with its sales figure

// C++ program that determines which of a company's four divisions (North, South, East, West) has the greatest sales for the quarter.

#include <iostream>

#include <limits>

#include <iomanip>

using namespace std;

// function declaration

float getSales(string name);

void validate(float &sales);

void findHighest(float northSales, float southSales, float eastSales, float westSales);

int main() {

               float northSales,southSales,eastSales,westSales;

               // get the quarterly sales for the divisions

               northSales = getSales("North");

               southSales = getSales("South");

               eastSales = getSales("East");

               westSales = getSales("West");

               // find the division with the highest sales

               findHighest(northSales,southSales,eastSales,westSales);

               return 0;

}

// function to get the quarterly sales for the passed division

float getSales(string name)

{

               float sales;

               cout<<"\n Enter the quarterly sales for "<<name<<" division : ";

               validate(sales);

               return sales;

}

// function to validate the input and return valid input

// argument is passed by reference

void validate(float &sales)

{

               cin>>sales;

               // in case of input error (sales negative or out of range)

               while(cin.fail() || sales < 0)

               {

                              cin.clear(); // clears the error flags

                              cin.ignore(std::numeric_limits<std::streamsize>::max(),'\n'); // and remove the bad input

                              cout<<" Invalid sales. Enter quarterly sales : ";

                              cin>>sales;

               }

}

// function to determine and print the division with the highest sales

void findHighest(float northSales, float southSales, float eastSales, float westSales)

{

               string highestName = "North";

               float highestSales = northSales;

               if(southSales > highestSales)

               {

                              highestSales = southSales;

                              highestName = "South";

               }

               if(eastSales > highestSales)

               {

                              highestSales = eastSales;

                              highestName = "East";

               }

               if(westSales > highestSales)

               {

                              highestSales = westSales;

                              highestName = "West";

               }

               cout<<"\n Highest grossing division : "<<highestName<<" Sales figure : "<<highestSales<<endl;

}

//end of program

Output:
