#includeThis code creates a `std::list` with characters 'a', 'b', and 'c'. It then obtains a reference to the first element of the list using `myList.front()` and assigns it to `frontElement`. The code then modifies `frontElement` to value 'd' and prints the updated first element of the list. Both examples utilize the `std::list` container provided in the C++ Standard Template Library (STL) and use the `std::list::front()` function to obtain the first element of the list.#include int main() { std::list
myList = {'a', 'b', 'c'}; char& frontElement = myList.front(); std::cout << "Front element of the list: " << frontElement << std::endl; frontElement = 'd'; std::cout << "Updated front element of the list: " << myList.front() << std::endl; return 0; }
