    Re: What is scope resolution operator?

    The :: (scope resolution) operator is used to qualify hidden names so that you can still use them. You can use the unary scope operator if a namespace scope or global scope name is hidden by an explicit declaration of the same name in a block or class.

    Re: What is scope resolution operator?

    The scope resolution operator helps to recognize and specify the context to which an identifier relates, particularly by specifying a namespace. The particular uses differ across different development 'languages' with the thoughts of scoping.

    Re: What is scope resolution operator?

    Scope resolution operator(: is used to define a function outside a class or when we want to use a global variable but also has a local variable with same name.
    C++ programming code
    #include <iostream>

    using namespace std;

    char c = 'a'; // global variable

    int main() {
    char c = 'b'; //local variable

    cout << "Local variable: " << c << "\n";
    cout << "Global variable: " << ::c << "\n"; //using scope resolution operator

    return 0;
