does C++ have spread operator?

can you do this in C++:

vector<int> v1={1,2}, v2={3,4};
vector<int> v3={...v1, ...v2, 5};
//v3 = {1,2,3,4,5}

What is the simplest way to do this with C++ ?

>Solution :

No spread operator in C++.

Probably the simplest way would be a sequence of inserts

std::vector<int> v3;
v3.insert(v3.end(), v1.begin(), v1.end());
v3.insert(v3.end(), v2.begin(), v2.end());
v3.insert(v3.end(), 5);

Various range libraries have a concat function

auto v3 = ranges::views::concat(v1, v2, { 5 }) | 
          ranges::views::join | 
          ranges::views::to<vector>; 

C++23 or ranges::v3. Still more verbose than spread operator.
