C++ Scope resolution operator
The scope resolution operator ( :: ) is used for several reasons. For example: If the global variable name is same as local variable name, the scope resolution operator will be used to call the global variable. It is also used to define a function outside the class and used to access the static variables of class.
Here an example of scope resolution operator in C++ language,
Example
#include <iostream>
using namespace std;
char a = 'm';
static int b = 50;
int main() {
char a = 's';
cout << "The static variable : "<< ::b;
cout << "\nThe local variable : " << a;
cout << "\nThe global variable : " << ::a;
return 0;
}Output
Here is the output
The static variable : 50 The local variable : s The global variable : m
