How do I use emplace vs push with std::list?

In C++, both `emplace` and `push` methods are used to add elements to a `std::list`, but they operate slightly differently. The `emplace` method constructs the element in place, allowing for more efficient memory usage as it can circumvent the need for copying or moving the object. On the other hand, the `push_back` and `push_front` methods simply push a copy (or move) of an existing object to the end or front of the list, respectively.

Here’s a basic example demonstrating the differences between `emplace` and `push` in a `std::list`:


        #include 
        #include 
        #include 

        int main() {
            std::list<:string> myList;

            // Using push_back to add an element
            myList.push_back("Hello");

            // Using emplace_back to add an element
            myList.emplace_back("World");

            // Printing the elements in the list
            for (const auto& str : myList) {
                std::cout << str << std::endl;
            }

            return 0;
        }
