Assume the declaration of Exercise.

a. Write the definition of the default constructor of yClass so that the private data members of yClass are initialized to 0 .

b. Write the definition of the default constructor of xClass so that the private data members of xClass are initialized to 0 .

c. Write the definition of the member function two of yClass so that the private data member a is initialized to the value of the first parameter of two, and the private data member b is initialized to the value of the second parameter of two .

Exercise

Consider the following statements:

class yClass{public:void one( );void two(int, int);yClass ( );private:int a;int b;};class xClass: public yClass{public:void one ( );xClass ( );private:int z;};yClass y;xClass x;

a. The private members of yClass are public members of xClass . True or False?

---

b. Mark the following statements as valid or invalid. If a statement is invalid, explain why.

i.

void yClass::one ( ){cout ≪ a + b ≪ end1;}

ii.

y.a = 15;x.b = 30;

iii.

void xClass::one ( ){a = 10;b = 15;z = 30;cout ≪ a + b + z ≪ end1;}

iv.

cout ≪ y.a ≪ “ ” ≪ y.b ≪ “ ” ≪ x.z ≪ end1;
