How to add a range of elements of a vector to another vector at a specific position in C++

Answer 1

#include <iostream>
#include <vector>

int main() {
    std::vector<int> source = {10, 20, 30, 40, 50, 60, 70};
    std::vector<int> target = {1, 2, 3, 4};

    // Insert elements from index 2 to 4 (30, 40, 50) into target at position 1
    target.insert(target.begin() + 1, source.begin() + 2, source.begin() + 5);

    for (int val : target) {
        std::cout << val << " ";
    }
}
