1: This program demonstrates the use of pointers. What is the output of this program? Assume we know that the initial address of x is 0012FF44.

 

#include <iostream>

using namespace std;

int main()

{

int x=25;

int *ptr; // pointer

ptr=&x;

cout<<x<<endl;

cout<<*ptr<<endl;

cout<<ptr<<endl;

//Now we assign 100 to x

*ptr=100;

cout<<endl;

cout<<"Now we assign 100 to x:"<<endl;

cout<<x<<endl;

cout<<*ptr<<endl;

cout<<ptr<<endl;

return 0;

}
