How to insert an array into at the beginning of a list in C++

Answer 1

#include <iostream>
#include <list>

void printList(std::list<int> const &l) {
    for (auto const &n: l) {
        std::cout << n << " ";
    }
}

int main() {
    std::list<int> l = { 5, 2, 7, 1, 9, 3, 6, 4 };
    int arr[]= { 100, 200, 300, 400 };

    l.insert(l.begin(), arr, arr + 6);      
    
    printList(l);
    
    return 0;
}
