We can also use the using keyword, so we don’t have to keep using the full name. In C++, the global namespace is the root namespace. global::std … Read more
Understanding C++ Namespaces: Definition, Use, and Scope Resolution In C++ programming, namespaces are an important feature used to resolve identifier conflicts. As the scale of the program increases, the number of functions, classes, and variables in the code also grows, which may lead to naming conflicts. To address this issue, C++ introduced the concept of … Read more

For example: #include <iostream> namespace Outer { namespace Inner { void printMessage() { std::cout << "This is a message from the Inner namespace." << std::endl; } } } int main() { Outer::Inner::printMessage(); return 0; } In this code, … Read more
