Question

How can you selectively include specific members from a namespace without using the entire namespace?

Answer 1

Instead of using using namespace <namespace_name>; to include the entire namespace, you can selectively include specific members from the namespace using the using declaration. For example, using std::cout; allows you to directly use cout from the std namespace without bringing in all other members.

Example:

#include <iostream>

using std::cout;

int main() {
    cout << "Hello, World!";
    return 0;
}
