}

 What will happen in this code? 

int a = 100, b = 200;

     int *p = &a, *q = &b;

     p = q;

Which of the following is the correct way to assign values to a forward_list f?

#include<stdio.h>

int main()

{

int a[10][20][30] = {0};

a[5][2][1] = 2;

return 0;

}

#include <iostream>
using namespace std;

int divide (int a, int b=2)
{
 int r;
 r=a/b;
 return (r);
}

int main ()
{
 cout << divide (12) ;
 cout << divide (20,4) << '\n';
 return 0;
}

What is the purpose of exception specification in C++?

 What will be the output of the following C code?

{

       a[0][1] = 3;

int i = 0, j = 0;

for (i = 0;i < 2; i++)

for (j = 0;j < 3; j++)

printf("%d", a[i][j]);

}

void main()

{

int a[2][3] = {0};

       f(a);

}
