Question
3. Consider the following statements: class yClass { public: void one(); void two(int, int); yClass(); private: int a; int b; }; class xClass: public yClass
3. 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 << endl;
}
ii. y.a = 15;
x.b = 30;
iii. void xClass::one()
{
a = 10;
b = 15;
z = 30;
cout << a + b + z << endl;
}
iv. cout << y.a << " " << y.b << " " << x.z << endl;
