I love C++ programming language for its power and complexity!! To me, its enormity and complexity has been an incessant source of different features to understand. C++ is still evolving, therefore, I'll have new stuff to learn for quite a while. Many of the C++ features are quite exotic and thats why I am interested in them. On this blog you will find exotic C++ stuff such as core language features, idioms, patterns, C++ emerging standards etc. This is not a beginners blog. You will find here intermediate to advanced level material on C++. I also plan to put new C++ material as I learn it. You might find thoughts presented here already presented somewhere else like popular C++ books, magazines, e-zines, websites, blogs etc. This is becasue I learn from these popular sources.

WhoamI?
I am not a guru in C++. But I put serious efforts into learning anything remotely related to C++.

Multi-dimensional arrays in C++11

What new can be said about multi-dimensional arrays in C++? As it turns out, quite a bit! With the advent of C++11, we get new standard library class std::array. We also get new language features, such as template aliases and variadic templates. So I'll talk about interesting ways in which they come together. It all started with a simple question of how to define a multi-dimensional std::array. It is a great example of deceptively simple things. Are the following the two arrays identical except that one is native and the other one is std::array? int native[3][4]; std::array<std::array<int, 3>, 4> arr; No! They are not. In fact, arr is more like an int[4][3]. Note the difference in the array subscripts. The native array is an array of 3 elements where every element is itself an array of 4 integers. 3 rows and 4 columns. If you want a std::array with the same layout, what you really need is: std::array<std::array<int, 4>, 3> arr; That's quite annoying for...

Review of Manning's Functional Programming in C++

Last year I reviewed the pre-print manuscript of Manning's Functional Programming in C++ written by Ivan Čukić. I really enjoyed reading the book. I enthusiastically support that the book Offers precise, easy-to-understand, and engaging explanations of functional concepts. Who is this book for This book expects a reasonable working knowledge of C++, its modern syntax, and semantics from the readers. Therefore, reading this book might require a companion book for C++ beginners. I think that’s fair because FP is an advanced topic. C++ is getting more and more powerful day by day. While there are many FP topics that could be discussed in such a book, I like the practicality of the topics selected in this book. Here's the table of contents at a glance. This is a solid coverage of functional programming concepts to get a determined programmer going from zero-to-sixty in a matter of weeks. Others have shared their thoughts on this book as well. See Rangarajan Krishnamo...

Want speed? Use constexpr meta-programming!

It's official: C++11 has two meta-programming languages embedded in it! One is based on templates and other one using constexpr . Templates have been extensively used for meta-programming in C++03. C++11 now gives you one more option of writing compile-time meta-programs using constexpr . The capabilities differ, however. The meta-programming language that uses templates was discovered accidently and since then countless techniques have been developed. It is a pure functional language which allows you to manipulate compile-time integral literals and types but not floating point literals. Most people find the syntax of template meta-programming quite abominable because meta-functions must be implemented as structures and nested typedefs. Compile-time performance is also a pain point for this language feature. The generalized constant expressions (constexpr for short) feature allows C++11 compiler to peek into the implementation of a function (even classes) and perform optimization...
