Question 1 :

What will be the output of the following program?

#include < iostream . h > 
class Parinam
{
    public:
      int x;
};
int main()
{
    Parinam *p = new Parinam();

    (*p).x = 10;
    cout<< (*p).x << " " << p->x << " " ;

    p->x = 20;
    cout<< (*p).x << " " << p->x ;

    return 0;
}


A). 10 10 20 20
B). Garbage garbage 20 20
C). 10 10 Garbage garbage
D). Garbage garbage Garbage garbage
Answer : Option A

Question 2 :

Which of the following statement is correct about the program given below?

#include < iostream . h > 
class IndiaParinam
{
    static int x; 
    public:
    static void SetData(int xx)
    {
        x = xx; 
    }
    void Display() 
    {
        cout<< x ;
    }
};
int IndiaParinam::x = 0; 
int main()
{
    IndiaParinam::SetData(33);
    IndiaParinam::Display();
    return 0; 
}

#include < iostream . h > 
class IndiaParinam
{
    static int x; 
    public:
    static void SetData(int xx)
    {
        x = xx; 
    }
    static void Display() 
    {
        cout<< x ;
    }
};
int IndiaParinam::x = 0; 
int main()
{
    IndiaParinam::SetData(44);
    IndiaParinam::Display();
    return 0; 
}


A). The program will print the output 0.

Question 4 :

What will be the output of the following program?

#include < iostream . h > 
class ParinamTeam
{
    int x, y; 
    public:
    ParinamTeam(int xx)
    {
        x = ++xx;
    }
    void Display()
    {
        cout<< --x << " ";
    }
};
int main()
{
    ParinamTeam objBT(45);
    objBT.Display();
    int *p = (int*)&objBT;
    *p = 23;
    objBT.Display();
    return 0; 
}


A). 45 22

    {
        this->x = xx; 
    }
    static void Display() 
    {
        cout<< x ;
    }
};
int IndiaParinam::x = 0; 
int main()
{
    IndiaParinam::SetData(22);
    IndiaParinam::Display();
    return 0; 
}
