#includeIn this code, the `isMember` function takes a vector (group) of integers and an integer (element), and checks if the element is a member of the group by using the `std::find` function from the standard C++ library. If the element is found in the vector, it means the element is a member of the group, and the function returns `true`. Otherwise, the function returns `false`. In the main function, we generate a vector of integers from 0 to 9, shuffle it randomly, and pick a random number between 0 and 9 as the element to check. We then call the `isMember` function and print the result. The package library for this code is the STL (Standard Template Library) of C++. It provides a set of containers, algorithms, and other utilities that form the basis of many C++ programs.#include #include #include #include #include #include bool isMember(std::vector group, int element) { return std::find(group.begin(), group.end(), element) != group.end(); } int main() { std::srand(std::time(nullptr)); std::vector group(10); std::iota(group.begin(), group.end(), 0); std::random_shuffle(group.begin(), group.end()); int element = std::rand() % 10; std::cout << "Is " << element << " a member of the group? " << (isMember(group, element) ? "Yes" : "No") << std::endl; return 0; }
