How to Slice a List in C++ ?

Answer

To slice a list in C++, you can use iterators and the std::advance function to specify the start and end positions.

✐ Examples

1 Slice a List of Integers

In this example,

We create a list named numbers with integer values.
We define iterators to specify the start and end positions for the slice.
We use the std::advance function to advance the iterators to the desired positions.
We create a new list named slicedNumbers using the iterators.
Finally, we print the sliced list to standard output.

C++ Program

#include <iostream>
#include <list>

int main() {
    std::list<int> numbers = {1, 2, 3, 4, 5};
    auto start = numbers.begin();
    auto end = numbers.begin();
    std::advance(start, 1);
    std::advance(end, 4);
    std::list<int> slicedNumbers(start, end);
    for (int num : slicedNumbers) {
        std::cout << num << " ";
    }
    std::cout << std::endl;
    return 0;
}

Output

2 3 4

2 Slice a List of Strings

In this example,

We create a list named words with string values.
We define iterators to specify the start and end positions for the slice.
We use the std::advance function to advance the iterators to the desired positions.
We create a new list named slicedWords using the iterators.
Finally, we print the sliced list to standard output.

C++ Program

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

int main() {
    std::list<std::string> words = {"apple", "banana", "cherry", "date", "elderberry"};
    auto start = std::next(words.begin(), 1);
    auto end = std::next(words.begin(), 4);
    std::list<std::string> slicedWords(start, end);
    for (const std::string& word : slicedWords) {
        std::cout << word << " ";
    }
    std::cout << std::endl;
    return 0;
}

Output

banana cherry date
