In this article we will learn to implement a CPP program to illustrate scope resolution new and delete operators. A C++ program is given below to demonstrate scope resolution operator, new operator and delete operators.
Program is as follows:
#include <iostream>
using namespace std;
int x = 20;
int main()
{
int x = 10;
cout<<"Local x = "<<x<<endl;
cout<<"Global x = "<<::x<<endl; //Scope resolution operator ::
int *p;
p = new int; //new operator
*p = 10;
cout<<"p = "<<*p;
delete(p); //delete operator
return 0;
}
Output for the above program is as follows:
Local x = 10
Global x = 20
p = 10

sir we used delete operator here…but in the output we are still getting the value of p.can u give much clarity about this…..??
We are printing value of p before calling delete operator. So we are able to see the value of p in the output.
