Scope Resolution Operator Example Program

// Header Files
#include<iostream>
#include<conio.h>
#include<stdio.h>

//Main Function

using namespace std;

int a = 100; //Global variable

int main ()
{
	// Local Variable Declaration
    int a = 200;
    
    cout << "Simple Scope Resolution Example Program In C++\n";
    
    // Print Global Varibale
    cout << ::a<< endl; 
    
    // Print Local Varibale
    cout << a << endl;

	//Main Function return Statement
	return 0;
}
