Question

Define the missing function. licenseNum is created as: (100000 * customID) + licenseYear. Sample output:

Answer 1

#include <iostream>

using namespace std;

class DogLicense {

  public:

     void   SetYear(int yearRegistered);

     void   CreateLicenseNum(int customID);

     int    GetLicenseNum() const;

  private:

     int    licenseYear;

     int    licenseNum;

};

void DogLicense::SetYear(int yearRegistered) {

  licenseYear = yearRegistered;

}

// FIXME: Write CreateLicenseNum()

void DogLicense::CreateLicenseNum(int customID) {

   licenseNum = (100000 * customID) + licenseYear;

}

int DogLicense::GetLicenseNum() const {

  return licenseNum;

}

int main() {

  DogLicense dog1;

  int userYear;

  int userId;

  cin >> userYear;

  cin >> userId;

  dog1.SetYear(userYear);

  dog1.CreateLicenseNum(userId);

  cout << "Dog license: " << dog1.GetLicenseNum() << endl;

  return 0;

}

Answer 2

Answer:

#include <iostream>

using namespace std;

class DogLicense{

   public:

       void SetYear(int yearRegistered);

       void CreateLicenseNum(int customID);

       int GetLicenseNum() const;

   private:

       int licenseYear;

       int licenseNum;

};

void DogLicense::SetYear(int yearRegistered) {

   licenseYear = yearRegistered;

}

void DogLicense::CreateLicenseNum(int customID) {

   licenseNum = (100000 * customID) + licenseYear;

}

int DogLicense::GetLicenseNum() const {

   return licenseNum;

}

int main() {

   DogLicense dog1;

   dog1.SetYear(2014);

   dog1.CreateLicenseNum(777);

   cout << "Dog license: " << dog1.GetLicenseNum() << endl;

return 0;

}

Explanation:

You can see the whole code above, but let me explain the fixed function.

void DogLicense::CreateLicenseNum(int customID) {

   licenseNum = (100000 * customID) + licenseYear;

}

The function header is already declared in the class. It takes customID as a parameter. To find out the lisenseNum, we need to apply the given formula (100000 * customID) + licenseYear.
