What is the output of the following C++
#include <iostream>
#include <string>
using namespace std;
class baseClass
{
public:
void print() const;
baseClass(string s = " ", int a = 0);
//Postcondition: str = s; x = a;
protected:
int x;
private:
string str;
};
class derivedClass: public baseClass
{
public:
void print() const;
derivedClass(string s = "", int a = 0, int b = 0);
//Postcondition: str = s; x = a; y = b;
private:
int y;
};
int main()
{
baseClass baseObject("This is the base class", 2);
derivedClass derivedObject("DDDDDD", 3, 7);
baseObject.print();
derivedObject.print();
system("pause");
return 0;
}
void baseClass::print() const
{
cout << x << " " << str << endl;
}
baseClass::baseClass(string s, int a)
{
str = s;
x = a;
}
void derivedClass::print() const
{
cout << "Derived class: " << y << endl;
baseClass::print();
}
derivedClass::derivedClass(string s, int a, int b) :
baseClass("Hello Base", a + b)
{
y = b;
}
