==== Garbage Collection ====

Traditional C++ does not have garbage collection.

After using `new` to allocate an object, use `delete` to deallocate it.

After using <code>new</code> to allocate an object, use <code>delete</code> to deallocate it.

You can also use C allocation with `malloc`, `calloc`, `alloca`, and `free`.

You can also use C allocation with <code>malloc</code>, <code>calloc</code>, <code>alloca</code>, and <code>free</code>, though it is [https://stackoverflow.com/questions/184537/in-what-cases-do-i-use-malloc-and-or-new not recommended] since these are not type-safe.

~~If using~~ C++14, you can use [https://en.cppreference.com/w/cpp/memory/shared_ptr shared pointers] which does have automatic garbage collection.

In C++14, you can use [https://en.cppreference.com/w/cpp/memory/shared_ptr shared pointers] which does have automatic garbage collection.
