Learn How To Use Binary Literals In Modern C++

C++14 brings us fewer but useful features to modern C++ than the standards preceding it. The creator of C++, Bjarne Stroustrup says that improvements in C++14 were deliberately lower in quantity compared to C++11. One of the small but useful features is the introduction of “Binary Literals”. C++14 comes with the Binary Literals feature, and in this post, we explain how we can use binary bits. 

Learn how to use binary literals in modern C++

binary literal is an integer literal that your binary number begins with 0b or 0B and consists of a sequence of binary digits (base two). It is defined in <bitset> and provides a convenient way to represent a binary base-2 number (1 and 0), useful for the developers in IDE, and useful to compilers that understand it is a binary value.

Here is a simple example of how we can use it.

Is there a simple example about how to use binary literals in modern C++?

We can use it with digital separators, which are another feature of C++. Here is an example, this time we used constants.

Note that, we can NOT use digital separator after the 0b literal as below.
