How to Append an Element to a List in C++ ?

Answer

To append an element to a list in C++ using std::list, you can use the push_back method.

✐ Examples

1 Append an Element to a std::list

In this example,

We include the necessary headers: and .
We create a std::list named numbers with initial integer values.
We use the push_back method of the std::list numbers to append a new integer to the list.
The push_back method modifies the original list by adding the new element at the end.
Finally, we use a range-based for loop to print the updated list to standard output.

C++ Program

#include <iostream>
#include <list>

int main() {
    std::list<int> numbers = {1, 2, 3, 4};
    numbers.push_back(5);
    std::cout << "Updated list: ";
    for (int number : numbers) {
        std::cout << number << " ";
    }
    std::cout << std::endl;
    return 0;
}

Output

Updated list: 1 2 3 4 5

2 Append Multiple Elements to a std::list

In this example,

We include the necessary headers: and .
We create a std::list named numbers with initial integer values.
We define another std::list named new_elements containing elements to be appended.
We use the insert method to add all elements from new_elements to the end of numbers.
Finally, we use a range-based for loop to print the updated list to standard output.

C++ Program

#include <iostream>
#include <list>

int main() {
    std::list<int> numbers = {1, 2, 3, 4};
    std::list<int> new_elements = {5, 6, 7};
    numbers.insert(numbers.end(), new_elements.begin(), new_elements.end());
    std::cout << "Updated list: ";
    for (int number : numbers) {
        std::cout << number << " ";
    }
    std::cout << std::endl;
    return 0;
}

Output

Updated list: 1 2 3 4 5 6 7
