What will be the output of the following C++ code?
#include <iostream>
using namespace std;
class Parent
{
public:
Parent (void)
{
cout << "Parent()\n";
}
Parent (int i)
{
cout << "Parent("<< i << ")\n";
};
Parent (void)
{
cout << "~Parent()\n";
};
};
class Child1 : public Parent { };
class Child2 : public Parent
{
public:
Child2 (void)
{
cout << "Child2()\n";
}
Child2 (int i) : Parent (i)
{
cout << "Child2(" << i << ")\n";
}
~Child2 (void)
{
cout << "~Child2()\n";
}
};
int main (void)
{
Child1 a;
Child2 b;
Child2 c(42);
return 0;
}
#include <iostream>
using namespace std;
class Parent
{
public:
Parent (void)
{
cout << "Parent()\n";
}
Parent (int i)
{
cout << "Parent("<< i << ")\n";
};
Parent (void)
{
cout << "~Parent()\n";
};
};
class Child1 : public Parent { };
class Child2 : public Parent
{
public:
Child2 (void)
{
cout << "Child2()\n";
}
Child2 (int i) : Parent (i)
{
cout << "Child2(" << i << ")\n";
}
~Child2 (void)
{
cout << "~Child2()\n";
}
};
int main (void)
{
Child1 a;
Child2 b;
Child2 c(42);
return 0;
}A. Parent()
Parent()
Child2()
Parent(42)
Child2(42)
~Child2()
~Parent()
~Child2()
~Parent()
~Parent()
B. error
C. runtime error
D. Parent(42)
