In C++ Builder sorting text string lines is very easy by setting Sorted property of a StringList to true. This example below sorts a given text file and saves as sorted in same name.
void sort_textfile(UnicodeString filename)
{
auto str_list = new TStringList;

There is no word to say, we would like to share this Amazing 3D Spinning Donut by Andy Sloane . This full post explains what is mathematic behind this. Please visit his awesome post here. There is also another video of his codes by Professor Lex Fridman here. We just made…
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…
Lambda Expressionsare an expression that returns a function object, it comes with C++11 standards and used C++14, C++17, C++20 standards, it is well explainedhere. Lambda expressions are widely used in C++, C#, Groovy, Java, Python, Ruby languages too.

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…
