#include#include using namespace std; int main() { set mySet = {5, 10, 15}; cout << "The size of the set is: " << mySet.size() << endl; return 0; }
The size of the set is: 3
#include#include using namespace std; int main() { set mySet; if (mySet.empty()) { cout << "The set is empty." << endl; } else { cout << "The set is not empty." << endl; } return 0; }
The set is empty.In this example, we create an empty set container and check if it is empty using the empty method. If it is empty, we print a message indicating that the set is empty. Overall, C++ set size is a simple and useful method for retrieving the number of elements in a set container. It is part of the
