When there are two variables with the same name but different scope, i.e. one is a local variable and the other is a global variable, the compiler will give preference to a local variable.

In order to access the global variable, we make use of a “scope resolution operator (::)”. Using this operator, we can access the value of the global variable.



int x= 10;

int main()


 int x= 2;

 cout<<”Global Variable x = “<<::x;

 cout<<”\nlocal Variable x= “<<x;



Global Variable x = 10

local Variable x= 2
