Question

Having problem with this code, it works but does not pass the "Testing if function PromptForInteger is valid... " test.   Below is the assignment, codethat I have so far, and the output. Thanks.

20.2 C++: Calculate salary: Using functions.

Separating calculations into functions simplifies modifying and expanding programs.

The following program calculates the tax rate and tax to pay, using functions. One function returns a tax rate based on an annual salary.

Run the program below with annual salaries of 40000, 60000, and 0.

Change the program to use a function to input the annual salary. The function MUST be called "PromptForInteger" and it must have as an argument a string.

Run the program again with the same annual salaries as above. Are results the same?

#include <iostream>
#include <vector>
#include <stdexcept>
using namespace std;

int PromptForInteger(const string userPrompt);

double GetCorrespondingTableValue(int search, vector<int> baseTable, vector<double> valueTable) {
   int baseTableLength = baseTable.size();
   double value = 0.0;
   int i = 0;
   bool keepLooking = true;

   while ((i < baseTableLength) && keepLooking) {
      if (search <= baseTable.at(i)) {
         value = valueTable.at(i);
         keepLooking = false;
      }
      else {
         ++i;
      }
   }

   return value;
}

int main() {
   int annualSalary = 0;
   double taxRate = 0.0;
   int taxToPay = 0;
   int i = 0;
   vector<int> salaryBase(5);
   vector<double> taxBase(5);

   salaryBase.at(0) = 0;
   salaryBase.at(1) = 20000;
   salaryBase.at(2) = 50000;
   salaryBase.at(3) = 100000;
   salaryBase.at(4) = 99999999;

   taxBase.at(0) = 0.0;
   taxBase.at(1) = 0.10;
   taxBase.at(2) = 0.20;
   taxBase.at(3) = 0.30;
   taxBase.at(4) = 0.40;

   // FIXME: Change the input to come from a function
   cout << " Enter annual salary (negative to exit): " << endl;
   cin >> annualSalary;

   while (annualSalary > 0) {
      taxRate = GetCorrespondingTableValue(annualSalary, salaryBase, taxBase);

      taxToPay = static_cast<int>(annualSalary * taxRate); // Truncate tax to an integer amount
      cout << "Annual salary: " << annualSalary <<" "<<
              "Tax rate: " << taxRate << " "<<
              "Tax to pay: " << taxToPay << endl;

      // Get the next annual salary
      // FIXME: Change the input to come from a function
      cout << " Enter annual salary (negative to exit): " << endl;
      cin >> annualSalary;
   }

   return 0;
}

Explanation / Answer

Here is your code corrected and added the function PromptForInteger.
#include <iostream>
#include <vector>
#include <stdexcept>
using namespace std;

int PromptForInteger(const string userPrompt)
{
int aSal =0; // declare a variable
cout << " " << userPrompt;
cin >> aSal; // Accept the input from the user.
return aSal; // return the input value to the calling function.
}

double GetCorrespondingTableValue(int search, vector<int> baseTable, vector<double> valueTable) {
int baseTableLength = baseTable.size();
double value = 0.0;
int i = 0;
bool keepLooking = true;

while ((i < baseTableLength) && keepLooking) {
if (search <= baseTable.at(i)) {
value = valueTable.at(i);
keepLooking = false;
}
else {
++i;
}
}

return value;
}

int main() {
int annualSalary = 0;
double taxRate = 0.0;
int taxToPay = 0;
int i = 0;
vector<int> salaryBase(5);
vector<double> taxBase(5);

salaryBase.at(0) = 0;
salaryBase.at(1) = 20000;
salaryBase.at(2) = 50000;
salaryBase.at(3) = 100000;
salaryBase.at(4) = 99999999;

taxBase.at(0) = 0.0;
taxBase.at(1) = 0.10;
taxBase.at(2) = 0.20;
taxBase.at(3) = 0.30;
taxBase.at(4) = 0.40;

// FIXME: Change the input to come from a function
// cout << " Enter annual salary (negative to exit): " << endl; I have commented it.
// cin >> annualSalary; You can delete these.
annualSalary = PromptForInteger("Enter annual salary (negative to exit): ");
while (annualSalary > 0) {
taxRate = GetCorrespondingTableValue(annualSalary, salaryBase, taxBase);

taxToPay = static_cast<int>(annualSalary * taxRate); // Truncate tax to an integer amount
cout << "Annual salary: " << annualSalary <<" "<<
"Tax rate: " << taxRate << " "<<
"Tax to pay: " << taxToPay << endl;

// Get the next annual salary
// FIXME: Change the input to come from a function
// cout << " Enter annual salary (negative to exit): " << endl; // you can delete these.
// cin >> annualSalary; as is the case.
annualSalary = PromptForInteger("Enter annual salary (negative to exit): ");
}

return 0;
}
