The pow() function returns:

What is the value of the following expression?

i = 1;

i = (i << 1) % 2

What will be the output?

#define x 10 * 10

#include <stdio.h>

int main()

{

    int a = x + x;

    printf("%d",a);

    return 0;

}

What is the output of the following code?

void main() { int i=2, j=2; while(i+1 ? --i : j++) printf("%d", i); }

Which access specifier makes all the data members and functions of the base class inaccessible to the derived class?

There are two types of polymorphism: compile-time polymorphism and runtime polymorphism. Runtime polymorphism can be achieved through:

Predict the output of the following program:

#include <stdio.h>

int fun(int n)

{

if (n == 4)

return n;

else return 2*fun(n+1);

}

int main()

{

printf("%d", fun(2));

return 0;

}

  What is the output of this C code?

int x = 5;
 void main()
    {
 int x = 3;
        m();
        printf("%d", x);
    }
 void m()
    {
        x = 8;
        n();
    }
 void n()
    {
        printf("%d", x);
    }

#include "stdio.h"

int * arrPtr[5];

int main()

{

if(*(arrPtr+2) == *(arrPtr+4))

{

printf("Equal!");

}

else

{

printf("Not Equal");

}

return 0;

}

What will be the output of the following C++ code?

#include <iostream>

#include <algorithm>

#include <vector>

using namespace std;

int main () 

{

int myints[] = {10, 20, 30, 30, 20, 10, 10, 20};

int mycount = count (myints, myints + 8, 10);

cout << "10 appears " << mycount << " times.\n";

       vector<int> myvector (myints, myints+8);

       mycount = count (myvector.begin(), myvector.end(), 20);

cout << "20 appears " << mycount  << " times.\n";

return 0;
