code — Syntax [crayon-5d5e8b9846c05483480436/] constexpr Before discussing about if-constexpr, we should discuss first about constexpr. It was introduced in C++11 to mark an expression as having a compile-time constant result. More about constexpr can be read here. if-constexpr if-constexpr simply add if statements at compile time. This way, we can get rid […]

huffman — Hello everyone, let’s talk about the Huffman encoding. The algorithm was taken from here and slightly modified to be more clear. As this algorithm is fairly simple and Internet is full of explanation regarding it, I will not go in too much detail. The algorithm is compressing the number of […]

code — Syntax [crayon-5d5e8b984817d491265606/] Usage / Usability Guarantees initialization at compile-time Used as a function qualifier before the function’s return type Conceptually, constexpr indicates a value that’s not only constant, it’s known during compilation. constexpr functions produce:compile-time constants (when they are called with compile-time constants) Runtime values (when they are called with […]
