#includeThis code uses the typeid() operator to get the name of the types of std::cout and std::cerr and compares them to see if they have the same QualifiedName. In this case, the package/library would be the C++ standard library (std) that provides functionality for basic operations in C++ such as input/output and containers. The boost library is also commonly used in C++ and provides additional functionality for things such as smart pointers, algorithms and template metaprogramming.int main() { if (typeid(std::cout).name() == typeid(std::cerr).name()) { std::cout << "std::cout and std::cerr have the same QualifiedName" << std::endl; } else { std::cout << "std::cout and std::cerr do not have the same QualifiedName" << std::endl; } return 0; }
