#includeIn this example, we create two lists, `first` and `second`, with `first` containing the elements 1, 2, and 3, and `second` containing the elements 4 and 5. We then use the `splice()` function to transfer all elements from `second` to `first`, starting at the position of the third element (`it`). Finally, we print the contents of both lists to the console. This function is part of the C++ Standard Library.#include using namespace std; int main() { list
first = {1, 2, 3}; list second = {4, 5}; auto it = first.begin(); advance(it, 2); //advance iterator to point to the third element in first list first.splice(it, second); // transfer all elements of second list to first list, starting from position "it" for (auto& x: first) cout << x << " "; cout << endl; for (auto& x: second) cout << x << " "; cout << endl; return 0; }
