Q2:
What will be the output of the program? 
#include<stdio.h>
int fun(int **ptr);

int main()
{
    int i=10;
    const int *ptr = &i;
    fun(&ptr);
    return 0;
}
int fun(int **ptr)
{
    int j = 223;
    int *temp = &j;
    printf('Before changing ptr = %5x\n', *ptr);
    const *ptr = temp;
    printf('After changing ptr = %5x\n', *ptr);
    return 0;
}
