Cpp Programming Quiz 154 – Which of the following statement is correct about the program given below?

#include
class BaseCounter
{
protected:
long int count;

public:
void CountIt(int x, int y = 10, int z = 20)
{
count = 0;
cout<< x << " " << y << " " << z << endl; } BaseCounter() { count = 0; } BaseCounter(int x) { count = x ; } }; class DerivedCounter: public BaseCounter { public: DerivedCounter() { } DerivedCounter(int x): BaseCounter(x) { } }; int main() { DerivedCounter objDC(30); objDC.CountIt(40, 50); return 0; }

[A].30 10 20
[B].Garbage 10 20
[C].40 50 20
[D].20 40 50

Answer: Option C

#include
class Base
{
public:
int S, A, M;
Base(int x, int y)
{
S = y - y;
A = x + x;
M = x * x;
}
Base(int, int y = 'A', int z = 'B')
{
S = y;
A = y + 1 - 1;
M = z - 1;
}
void Display(void)
{
cout<< S << " " << A << " " << M << endl; } }; class Derived : public Base { int x, y, z; public: Derived(int xx = 65, int yy = 66, int zz = 67): Base(x) { x = xx; y = yy; z = zz; } void Display(int n) { if(n) Base::Display(); else cout<< x << " " << y << " " << z << endl; } }; int main() { Derived objDev; objDev.Display(-1); return 0; }

[A].65 65 65
[B].65 66 67
[C].A A A
[D].A B C

Answer: Option A
