#include#include using namespace std; int main() { set mySet; // create a CKey Set of type int // add some keys mySet.insert(10); mySet.insert(20); mySet.insert(30); mySet.insert(40); // print all keys in the set for (const auto& key : mySet) { cout << key << endl; } return 0; }
#includeIn this example, we create a CKey Set of type string and add some string keys to it using the `insert()` method. We then remove the key "banana" from the set using the `erase()` method. Finally, we iterate through the set using a range-based for loop and print out all the remaining keys. CKey Set is part of the C++ Standard Template Library (STL) package.#include using namespace std; int main() { set mySet; // create a CKey Set of type string // add some keys mySet.insert("apple"); mySet.insert("banana"); mySet.insert("cherry"); mySet.insert("date"); // remove a key mySet.erase("banana"); // print all keys in the set for (const auto& key : mySet) { cout << key << endl; } return 0; }
