Create and delete
You can construct each container by a multitude of constructors. To delete all elements of a container cont, you can use cont.clear(). It makes no difference if you create a container, if you delete them or if you add or remove elements. Each time the container takes care of the memory management.
The table shows you the constructors and destructors of a container. A std:vector stands for the rest of them.
| Type | Example |
|---|---|
| Default | std::vector<int> vec1 |
| Range | std::vector<int> vec2(vec1.begin(), vec1.end()) |
| Copy | std::vector<int> vec3(vec2) |
| Copy | std::vector<int> vec3= vec2 |
| Move | std::vector<int> vec4(std::move(vec3)) |
| Move | std::vector<int> vec4= std::move(vec3) |
| Sequence (Initializer list) | ...
