Overloading Operator new and delete 2

I overloaded in the last post operator new and delete. Therefore, it was possible to find memory leaks and get a first hint of the bad guys. My solution had two not so nice properties. With this post, I will overcome them.

Overloading Operator new and delete 1

It happens quite to often that a C++ application allocates memory but don't deallocate it. This is the job for operator new and delete. Thanks to them both you can explicitly manage the memory management of an application.

Explicit Memory Management

Explicit memory management has in C++ a high complexity but also provides a great functionality. Sad to say, but this special domain in not so known in C++. For example, you can directly create objects in static memory, in a reserved area, or even in a memory pool. That is functionality, that is often key in safety critical applications in the embedded world. Before the harvest is the work. Therefore, I will give in this post an overview, before I dive deeper into the details.

Garbage Collection - No Thanks

C++ is old fashioned. C++ has no garbage collection. No garbage collection? Right! Old fashioned? Wrong!

Time for Wishes

I wrote more than 130 posts in my German blog about functional programming, embedded programming and multithreading programming with modern C++. My English blog will catch up in two months with my German one. Therefore, it's the right time to rework my blogs. The German blog and the English blog in parallel.

Move Semantic: Two nice Properties

I will talk about two nice properties of the move semantic in this post that are not so often mentioned. Containers of the standard template library (STL) can have non-copyable elements. The copy semantic is the fallback for the move semantic. Irritated? I hope so!

Copy versus Move Semantic: A few Numbers

A lot was written about the advantages of the move semantic to the copy semantic. Instead of an expensive copy operation you can use a cheap move operation. But, what does that mean? I will compare in this post the performance of the copy and move semantic for the containers the Standard Template Library (STL).

std::array - Dynamic Memory, no Thanks

std::array combines the best from two worlds. At one hand, std::array has the size and efficiency of a C array; at the other hand, std::array has the interface of a std::vector.

Automatic Memory Management of the STL Containers

One of the big advantages of C++ string to a C string and of a std::vector to a C arrays is it that both C++ containers automatically manage their memory. Of course, that holds true for all further containers of the Standard Template Library. In this post, I will have a closer look at the automatic memory management of std::vector and std::string.
