How to Append a List to another List in C++ ?

Answer

To append a list to another list in C++ using std::list, you can use the insert function or the splice function.

✐ Examples

1 Append List Using insert Function

In this example,

We include the necessary headers: and .
We create two lists: list1 and list2 with initial values.
We use the insert function to insert all elements of list2 at the end of list1.
Finally, we print the updated list1 to standard output.

C++ Program

#include <iostream>
#include <list>

int main() {
    std::list<int> list1 = {1, 2, 3};
    std::list<int> list2 = {4, 5, 6};
    list1.insert(list1.end(), list2.begin(), list2.end());
    for (int num : list1) {
        std::cout << num << " ";
    }
    return 0;
}

Output

1 2 3 4 5 6

2 Append List Using splice Function

In this example,

We include the necessary headers: and .
We create two lists: list1 and list2 with initial values.
We use the splice function to transfer all elements of list2 to the end of list1.
Finally, we print the updated list1 to standard output.

C++ Program

#include <iostream>
#include <list>

int main() {
    std::list<int> list1 = {1, 2, 3};
    std::list<int> list2 = {4, 5, 6};
    list1.splice(list1.end(), list2);
    for (int num : list1) {
        std::cout << num << " ";
    }
    return 0;
}

Output

1 2 3 4 5 6
