Language/Type: C++ inheritance polymorphism

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

class Jesse : public Tulip {
public:
    virtual void m1() {
        cout << "Js1  ";
        Cassidy::m1();
    }

    virtual void m4() {
        cout << "Js4  ";
        m2();
    }
};

class Cassidy {
public:
    virtual void m1() {
        cout << "Ca1  ";
        m2();
    }

    virtual void m2() {
        cout << "Ca2  ";
    }
};

class Tulip : public Cassidy {
public:
    virtual void m2() {
        cout << "Tu2  ";
        Cassidy::m2();
    }

    virtual void m3() {
        cout << "Tu3  ";
        m1();
    }
};

Now assume that the following variables are defined: 

Cassidy*  var1 = new Tulip();
Tulip*    var2 = new Jesse();

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->m3();
var2->m2();
var2->m3();
var2->m4();
((Tulip*) var1)->m3();
((Tulip*) var1)->m4();
((Jesse*) var1)->m4();
((Cassidy*) var2)->m3();
((Jesse*) var2)->m4();
