#includeIn this example, we define a function called greet that takes a string and an integer as arguments. We then create a function pointer to the greet function using the std::function template. Next, we create a tuple that contains the argument values to pass to the greet function. Finally, we use the std::apply function to obtain the arguments from the tuple and call the function pointer. Based on the use of the `std::function` and `std::apply` functions, it can be determined that this code example is part of the C++ standard library.#include using namespace std; void greet(const string& name, int age) { cout << "Hello " << name << ", you are " << age << " years old!" << endl; } int main() { // Create a function pointer to the greet function function funcPtr = &greet; // Create an argument list for the greet function auto args = make_tuple("John Doe", 42); // Obtain the arguments using CallArgs and call the function apply(funcPtr, args); return 0; }
