Language/Type: C++ inheritance polymorphism

Consider the following classes; assume that each is defined in its own file. 

class Golbez : public Cecil {
public:
    virtual void m2() {
        cout << "Golbez m2" << endl;
        m1();
    }
};

class Rosa : public Cecil {
public:
    virtual void m3() {
        cout << "Rosa m3" << endl;
        m2();
    }
    
    virtual void m4() {
        cout << "Rosa m4" << endl;
    }
};

class Cecil : public Kain {
public:
    virtual void m1() {
        cout << "Cecil m1" << endl;
        Kain::m1();
    }

    virtual void m3() {
        cout << "Cecil m3" << endl;
        m2();
    }
};

class Kain {
public:
    virtual void m1() {
        cout << "Kain m1" << endl;
    }

    virtual void m2() {
        m1();
        cout << "Kain m2" << endl;
    }
};

Now assume that the following variables are defined: 

Kain*  var1 = new Cecil();
Cecil* var2 = new Rosa();
Kain*  var3 = new Golbez();
Cecil* var4 = new Golbez();

In the table below, indicate in the right-hand column the output produced by the statement in the left-hand column. If the statement produces more than one line of output, indicate the line breaks with slashes as in "x / y / z" to indicate three lines of output with "x" followed by "y" followed by "z". If the statement does not compile, write "COMPILER ERROR". If a statement would crash at runtime or cause unpredictable behavior, write "CRASH".

var1->m1();
var1->m2();
var1->m3();
var2->m3();
var3->m2();
var3->m4():
var4->m3();
((Cecil*) var1)->m3();
((Rosa*) var1)->m4();
((Rosa*) var2)->m4();
((Golbez*) var3)->m4();
