Which functional feature can we expect with C++17, for which functional feature can we hope for with C++20? This is exactly the question I will concisely answer in this post.

My favourite example the dispatch table shows how nice the features in modern C++ work together. A dispatch table is a table of pointers to functions. In my case, it is a table of handles to polymorphic function wrappers.

In this post, our journey through the functional features of classical, modern, and future C++ continues. Today, we stop in the present.

C++ is not a functional programming language but you can program in a functional style. What are the functional features in C++? I will answer this question for C++98.

C++ is not a functional programming language. C++ has its roots in the procedural and object-oriented programming. So it's quite surprising that programming in a functional style becomes more and more important in C++. That is not only true for C++. That holds also for python, which has a lot of functional features and even for Java. Now Java has lambda-functions.

After I have written a few posts about memory management in C++, I'm very glad to present Jonathan Müller, which will write a guest post about his implementation of the memory library. He will explain us his concepts about his design. Jonathan is known as an expert of memory management in the C++ community. In the  59 episode he presented his ideas to a world wide audiance.

In C++ you have the choice between various memory allocation strategies. In addition to the frequently used dynamic memory allocation you have the stack allocation. But you can preallocate the memory at the start time of your program. This can be a fixed sized block or one or more memory pools. Each of these strategies have its pros and cons. Which one, I will answer in this post.

There a lot of different strategies for allocating memory. Programming languages like Python or Java request their memory from the heap at runtime. Of course, C or C++ has also a heap but prefers the stack. But this are by far not so only strategies for allocating memory. You can preallocate memory at the start time of the program as a fixes block or as a pool of memory blocks. This preallocated memory can afterwards used at the runtime of your program. But the key question is. What are the pros and cons of the various strategies to allocate memory?

What is common between all containers of the Standard Template Library? They have a type parameter Allocator that is by default std::allocator. The job of the allocator is it to manage the lifetime of its elements. That means to allocate and deallocate memory for its elements and to initialize and destruct them.

In my post Time for Wishes I asked: "How can I improved my blog?" And here are the answers.
