Question

Have Corporate Sales for 6 divisions and their quarterly sales figures. The issue is the error function where I am unable to have user reinput the same quarterly amount without going to the next quarter input. This has affected the total sales for the company.

/*****************************************

This program gathers sales information

for six divisions and displays the total

sales for each division and total company.

#include<iostream>

using namespace std;

Here is updated code below: (We have to use while loop to iterate until user inputs correct value)

#include<iostream>

using namespace std;

// Classs division sales

class DivSales

{

private:

// Variables

int qrtSales[4];

static double totalSales;

public:

// DivSales();

void addQrtSales(int, int, int, int);

int sales(int);

static double getSales()

{

return totalSales;

}

};

// addQrtSales function

void DivSales::addQrtSales(int s1, int s2, int s3, int s4)

{

qrtSales[0] = s1;

qrtSales[1] = s2;

qrtSales[2] = s3;

qrtSales[3] = s4;

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

}

// Sales function

int DivSales::sales(int n)

{

int value = qrtSales[n];

return value;

}

// Validate input

void error()

{

cout << "\nYou have entered an invalid value\n";

system("pause");

}

// Initialize totalSales

double DivSales::totalSales = 0.00;

int main()

{

DivSales ds[6];

int i, j;

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

{

int s1, s2, s3, s4;

// Get input

cout << "\nEnter Sales Division: " << i + 1 << endl;

bool isCorrect1=true;

//Here we added a loop that will continue to iterate till a correct input is provided

//Same method is followed to get all inputs correctly

while(isCorrect1)

{

cout << "\nEnter Q1 Sales: ";

cin >> s1;

if (s1 < 0)

error();

else

{

isCorrect1 = false;

bool isCorrect2=true;

while(isCorrect2)

{

cout << "\nEnter Q2 Sales: ";

cin >> s2;

if (s2 < 0 || )

error();

else

{

isCorrect2 = false;

bool isCorrect3=true;

while(isCorrect3)

{

cout << "\nEnter Q3 Sales: ";

cin >> s3;

if (s3 < 0)

error();

else

{

isCorrect3= false;

bool isCorrect4=true;

while(isCorrect4)

{

cout << "\nEnter Q4 Sales: ";

cin >> s4;

if (s4 < 0)

error();

else

{

isCorrect4 = false;

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

}

}

}

}

} }

}

}

}

cout << "-----------------------------------\n";

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

cout << "-----------------------------------\n";

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

{

cout << "DIV" << i + 1;

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

{

cout << "\t" << ds[i].sales(j);

}

cout << endl;

}

cout << "-----------------------------------\n";

cout << "\nTotal All Division Sales for the Year: "

<< ds[0].getSales() << endl;

cout << endl;

system("pause");

return 0;

}
