Can we access global variable if there is a local variable with same name?
  • Difficulty Level : Easy
  • Last Updated : 22 Jan, 2021

In C, we cannot access a global variable if we have a local variable with same name, but it is possible in C++ using scope resolution operator (::)


// C++ Implementation
#include <iostream>
using namespace std;
int x; // Global x
int main()
    int x = 10; // Local x
    cout << "Value of global x is " << ::x << endl;
    cout << "Value of local x is " << x;
    return 0;


Value of global x is 0
Value of local x is 10
