How to Iterate Over a List in C++ ?

Answer

To iterate over a list in C++ using std::list, you can use an iterator to traverse through the elements of the list.

✐ Examples

1 Iterate Over List using Iterator

In this example,

We include the necessary header file for using std::list.
We create a list named numbers with integer elements.
We define an iterator it to iterate over the elements of the list.
We use a for loop to traverse the list using the iterator.
Within the loop, we access and print each element using the iterator.

C++ Program

#include <iostream>
#include <list>

int main() {
    std::list<int> numbers = {10, 20, 30, 40, 50};
    std::list<int>::iterator it;
    for (it = numbers.begin(); it != numbers.end(); ++it) {
        std::cout << *it << std::endl;
    }
    return 0;
}

Output
