How to get Element in a List at a Specific Index in C++ ?

Answer

To access an element in a std::list at a specific index in C++, you can use the std::advance function with an iterator.

✐ Examples

1 Access Element at Specific Index in std::list (C++)

In this example,

We create a std::list named numbers with integer elements.
We create a list iterator named it and advance it to the desired index using std::advance.
The element at the specified index is accessed using *it.
Finally, we print the accessed element to standard output.

C++ Program

#include <iostream>
#include <list>
#include <iterator>

int main() {
    std::list<int> numbers = {10, 20, 30, 40, 50};
    auto it = numbers.begin();
    std::advance(it, 2);
    std::cout << "Element at index 2 is: " << *it << std::endl;
    return 0;
}

Output

Element at index 2 is: 30
