Cpp Programming Quiz 129 – Which of the following statements is correct when a class is inherited privately?

#include
class IndiaBix
{
int K;
public:
void BixFunction(float, int , char);
void BixFunction(float, char, char);

};
int main()
{
IndiaBix objIB;
objIB.BixFunction(15.09, 'A', char('A' + 'A'));
return 0;
}
void IndiaBix::BixFunction(float, char y, char z)
{
K = int(z);
K = int(y);
K = y + z;
cout<< "K = " << K << endl; }

[A]. The program will print the output M = 130.
[B]. The program will print the output M = 195.
[C]. The program will print the output M = -21.
[D]. The program will print the output M = -61. 

Answer: Option D

#include
class Addition
{
int x;
public:
Addition()
{
x = 0;
}
Addition(int xx)
{
x = xx;
}
Addition operator + (int xx = 0)
{
Addition objTemp;
objTemp.x = x + xx;
return(objTemp);
}
void Display(void)
{
cout<< x << endl; } }; int main() { Addition objA(15), objB; objB = objA + 5; objB.Display(); return 0; }

[A].The program will print the output 20.
[B].The program will report run time error.
[C].The program will print the garbage value.
[D].Compilation fails due to 'operator +' cannot have default arguments. 

Answer: Option D

#include
class Base
{
int x, y;
public:
Base()
{
x = y = 0;
}
Base(int xx)
{
x = xx;
}
Base(int p, int q = 10)
{
x = p + q;
y = q;
}
void Display(void)
{
cout<< x << " " << y << endl; } }objDefault(1, 1); class Derived: public Base { Base obj; public: Derived(int xx, int yy): Base(xx, xx + 1) { } Derived(Base objB = objDefault) { } }; int main() { Derived objD(5, 3); Derived *ptrD = new Derived(objD); ptrD->Display();
delete ptrD;
return 0;
}

[A].3 2
[B].8 3
[C].11 6
[D].11 10 

Answer: Option C
