Delimiters (token term also used) are characters which separates strings between each of them. For example spaces, comas and other symbols can be used as a delimiter char to separate strings between them . Normaly in C++ strtok() were being used in C++, that is used with chars. In Modern C++, strings are now UnicodeStrings, TStringlists has some property to extract strings. If you are new to…
Learn C++ With Embedded: Customizing Dynamic Memory Management in C++ by Ben Saks (CPPCon 2020) Videos
December 18, 2020
For several common programming problems, Dynamic Memory Allocation is a normal solution. New-expressions in C++ places dynamic memory through a function called operator new. However, too many resource-stricted systems fully ignore the use of new-expressions for…
Bitmap is a standard for reading and writing pixels of images of applications on all platforms (Windows, MacOS, iOS, Android, Linux, …). A Bitmap includes bitmap information and full uncompressed image in pixels. Each pixel of this uncompressed image consists 4 color…
Learn C++ With C++20 STL Features: One Year of Development on GitHub by Stephan T. Lavavej (CPPCon 2020) Video
December 17, 2020
This video discusses the examples of C++20 features: span that makes it simpler to work with contiguous sequences, constexpr algorithms that make it possible to check if search tables are sorted at compiled time that eventually replaces the erase-move idiom, integer comparison features that make it easier to write correct code without thinking about the correct code. If you want to track progress…
Mobile android applications developed in C++ Builder requires permissions to use some part of mobile devices (sensors, camera etc..). These should be allowed by the user. an these permissions can be checked over the project options from Project > Options >…
If you are a beginner “Hello World” examples are good to understand feature of that programming language. It is good to understand how to edit text, how to write in its format, how to compile and link, how to debug and execute, how to deploy or release. This example below is a modern “Hello World” example on Windows which runs with C++ Builder. Modern applications has GUI…
Learn C++ With C++20: An (Almost) Complete Overview by Marc Gregoire (CPPCon 2020) Video
December 15, 2020
This video summarizes the C++20 language and its Standard Library. It tackles new enhancements on the standard library as well, including: ranges, atomic smart pointers, cancellable threads, a synchronization library, and more. The content of the discussion has been updated…

Every implementation of the C++ Standard Library like one included to Embarcadero RAD Studio C++ compilers provides two ways for (pseudo-)random numbers generation: old-fashioned facilities from <cstdlib> and modern facilities provided by <random>.
Facilities from <cstdlib>
There are two very simple functions provided by the C random library: std::srand() and std::rand().
