How to Join Lists in C++ ?

Answer

To join lists in C++ using `std::list`, you can use the `insert` method to combine multiple lists into a single list.

✐ Examples

1 Join Two Lists of Integers

In this example,

We create two lists named list1 and list2 with integer values.
We create a new list named joinedList and use the insert method to add all elements from list1 and list2 to joinedList.
Finally, we print the joined list to verify the result.

C++ Program

#include <iostream>
#include <list>

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

Output

Joined List: 1 2 3 4 5 6

2 Join Multiple Lists of Strings

In this example,

We create three lists named listA, listB, and listC with string values.
We create a new list named resultList and use the insert method to add all elements from listA, listB, and listC to resultList.
Finally, we print the joined list to verify the result.

C++ Program

#include <iostream>
#include <list>
#include <string>

int main() {
    std::list<std::string> listA = {"apple", "banana"};
    std::list<std::string> listB = {"cherry", "date"};
    std::list<std::string> listC = {"fig", "grape"};
    std::list<std::string> resultList;
    resultList.insert(resultList.end(), listA.begin(), listA.end());
    resultList.insert(resultList.end(), listB.begin(), listB.end());
    resultList.insert(resultList.end(), listC.begin(), listC.end());
    std::cout << "Joined List: ";
    for (const std::string& s : resultList) {
        std::cout << s << " ";
    }
    return 0;
}

Output

Joined List: apple banana cherry date fig grape
