Generic algorithms have been available in C++ for decades, but the last two versions of the language have really ramped up the functionality. C++17 added support for parallel execution of generic algorithms to easily take advantage of multi-core CPUs. Then C++20 added support for ranges, a composable version of generic algorithms that’s even closer to LINQ in C#. Today we’ll explore both of these!
The C++ Standard Library’s algorithms are culmination of a lot of C++ language and library features. They’re like a much more featureful, much faster version of LINQ in C#. This powerful combination makes most “raw” loops unnecessary as they can be replaced by named function calls that are well-tested and often compile to the same machine code as a “raw” loop. Read on to learn about them!
We’ve covered all the individual container types, so let’s take a step back and look at the containers library as a whole. A lot of features, like support for range-based
for loops and allocator customization, are supported in all container types. Today we’ll take a look at the commonalities between the containers and see what ties them together into a cohesive library.
We use certain container types, like maps and dynamic arrays, constantly. Others, like linked lists and queues, more sparingly. Still, they are fundamental structures in virtually every program and the poster children for generic programming. Like C#, the Standard Library in C++ provides a bunch of container types. Today we’ll start going through them, starting with containers for various kinds of arrays!
As C# includes classes like
Mutex, the C++ Standard Library also provides support for multi-threading. Classes like
std::mutex are very similar, but there are larger differences when it comes to C#’s
await keywords. Read on to learn how to write multi-threaded C++!
There are so many kinds of numbers we deal with on a regular basis and the C++ Standard Library has a full suite of tools to deal with them. Today we’ll look into random numbers, ratios, mathematical constants, bit manipulation, complex numbers, and more!
A programming language without access to the underlying system is of little use. Even a “Hello, world!” program requires the OS to output that message. Today we’ll start looking at the system access that the Standard Library provides. We’ll see how to access the file system, so-called “smart” pointers, and check the time using various system clocks.
