These are notes on what I need to fix.

/* Program not acceptable.

1. We do not allow global variables.

2. You never call the functions that you wrote.

3. What is the code in main doing? returning aboolean to whom?

4. You do not have any protypes.

*/

Please help me fix this c++ program:

#include

using namespace std;

bool validateInput(int number, double arg1, double arg2, double arg3, double arg4)

{

if (arg1

{

return false;

}

return true;

}

//calculate the interior Cost

double interiorCost(double sqft, double price)

{

return sqft*price;

}

//calculate the exterior Cost

double exteriorCost(double sqft, double price)

{

return sqft*price;

}

//calculate the totalCost post applying discount

double totalCost(double total)

{

//if price is greater than 1000, apply 10% discount

if(total >1000)

{

double totalCost=total*0.1;

return total-totalCost;

}

return total;

}

int main()

{

string name;

int value;

double intSqFt=0, extSqtFt=0;

double intRate=0, extRate=0;

ifstream inFile;

ofstream oFile;

ofstream eFile;

//declarartion for input, output, error files.

string fileName, outfile="output.txt", errorfile="error.txt";

cout

cin >> fileName;

//open the file name

//throw error if file opening has error

cout

exit(1);

inFile.close();

exit(1);

continue;

}

//calculate the total

double total = (interiorCost(intSqFt, intRate) + exteriorCost(extSqtFt, extRate));

double discount = 0;

//print the output to out file

This is the prompt:

Objectives To learn to code, compile and run a program containing two or more functions. Assignment Write a complete program to calculate painting costs for customers of Top Quality Home Painting Service. Function 1: Read the data for one job from a file (see data below). Validate that none of the numbers are negative. Return the data from good records to main and write error records onto a separate file. Function 2: Determine the cost for interior painting, the cost for exterior painting, and the cost for the entire paint job. Any painting estimate greater than $1000.00 receives a 10% discount. Return all calculated values to main. Function 3: Label and output all good data (customer initials, customer account number, interior square feet, cost per interior square feet, exterior square feet, cost per exterior square feet, total interior cost, total exterior cost, any discount and total cost) to the screen. Input Input data from a file. One record of data contains the following sequence of data: ABC 1234 400 3.50 850 5.50 3 customer initials, customer account number (4 digit integer), the number of interior square feet to be painted, the cost per square foot for interior painting, the number of exterior square feet to be painted, the cost per square foot for exterior painting.
