Optional definition (std::optional) manages anoptionalcontained value, i.e. a value that may or may not be present. This class templatecomes with C++17 standard, it is used with CLANG and other C++ compilers which has this standard. A common use case foroptionalis the return value of a function that may fail. Any instance ofoptional<T>at any given…
Inmathematics, Fractalsare a self-similar subset ofEuclidean space whose fractal dimensions strictly exceeds its topological dimension. So when you draw these functions in their topological height, fractals appear the same at different levels, as…

Quickly Learn To Search And Count Words From A Text File In Modern C++
February 6, 2021
C++ Builder is easy to operate on files on Windows. There are many methods to operate on files. Some of these methods are explained well in Windows File Operations in Modern C++. In this post we create a snippet to search and count a text from a text file.
unsigned int count_text(UnicodeString text, UnicodeString filename)
{
if(FileExists(filename))
{
UnicodeString us;
unsigned int…

Learn To Use Powerful Cryptographic Hash Functions In Modern C++ On Windows (SHA, SHA2, MD5, BobJenkins)
February 4, 2021
Cryptographic Hash Functionsare a one-way algorithm that takes an input of any size and produces the same size output. The cryptographic hash functions are a more secure version of the hash functions. It is one-way in that there is information loss — you can’t…
Learn To Easily Develop A Fun Fibonacci Number Generator In C++ For Windows
February 3, 2021
Fibonacci Numbers are sequence numbers called the Fibonacci sequence, and in mathematics, it starts with 0 and 1, and then each number is the sum of the two preceding ones. Fibonacci numbers are strongly related to Golden Ratio. In mathematics, two quantities are in the golden ratio if their ratio is the same as the ratio of their sum to the larger of two quantities. There is Binet’s…
Calculating prime numbers in a range is another comparison in programming languages. In this article, we compared the speed of codes to find Prime Number functions in C++ and Python
1. Introduction
Prime numbers are an interesting area to research. Aprime number…
