How to Reverse a List in C++ ?

Answer

To reverse a list in C++ using std::list, you can use the reverse function from the header.

✐ Examples

1 Reverse a List using std::reverse Function

In this example,

We have a list named originalList containing elements in the original order.
We include the necessary headers.
We use the std::reverse function to reverse the list.

C++ Program

#include <iostream>
#include <list>
#include <algorithm>

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

Output

Reversed list: 5 4 3 2 1

2 Reverse a List using std::reverse Function with String List

In this example,

We have a string list named originalList.
We include the necessary headers.
We use the std::reverse function to reverse the list.

C++ Program

#include <iostream>
#include <list>
#include <algorithm>

int main() {
    std::list<std::string> originalList = {"apple", "banana", "orange", "grape"};
    std::reverse(originalList.begin(), originalList.end());
    std::cout << "Reversed list:";
    for (const std::string& fruit : originalList) {
        std::cout << " " << fruit;
    }
    return 0;
}

Output

Reversed list: grape orange banana apple
