Write the PrintItem() function for the base class. Sample output for below program:

Last name: Smith
First and last name: Bill Jones

#include
#include
#include
using namespace std;
class BaseItem {
public:
void SetLastName(string providedName) {
lastName = providedName;
};
// FIXME: Define PrintItem() member function
/* Your solution goes here */
protected:
string lastName;
};
class DerivedItem : public BaseItem {
public:
void SetFirstName(string providedName) {
firstName = providedName;
};
void PrintItem() const override {
cout << "First and last name: ";
cout << firstName << " " << lastName << endl;
};
private:
string firstName;
};
int main() {
BaseItem* baseItemPtr = nullptr;
DerivedItem* derivedItemPtr = nullptr;
vector itemList;
unsigned int i; baseItemPtr = new BaseItem();
baseItemPtr->SetLastName("Smith" );
derivedItemPtr = new DerivedItem();
derivedItemPtr->SetLastName("Jon es");
derivedItemPtr->SetFirstName("Bi ll"); itemList. push_back(baseItemPtr); itemList. push_back(derivedItemPtr);
for (i = 0; i < itemList. size(); ++i) {
itemList. at(i)->PrintItem();
}
return 0;
}
