When I was very young and first learned about Pi they told me 3.14 was a good approximation, but it was an irrational number that went on forever, and people with computers were able to calculate many digits. I had a computer (Commodore Vic 20) and wanted to see how many digits of Pi I could calculate. This is when I discovered floating point number precision limitations, which foiled my first…
As a software developer, if you are focused on an application development project, as a professional you want to focus only on your project, your code, the UI, and your application’s runtime requirements. If your IDE is hard to handle it can cost a lot of time on…

Update: I revisited the calculation of Pi with even more digits.
In the United States today, March 14th is π day (3rd month, 14th day, or 3/14). Traditions involve eating pie, the pastry, and calculating Pi, the irrational mathematical constant.

Hello C++ and Delphi Developers,
Today we are looking at strings, mostly String Operations in your Modern C++ app. We also added some older functions or methods which are still popular C and C++ string operations that you come across while coding. We will learn to swap…
A C or C++ Compiler is a computer program that converts the text of a program’s code into an executable program. How can we check the version of the C++ compiler we are using on our Windows computer? Let’s take a look at a few different ways to do it.
How can…
Hello C++ Developers,
This week we have an abundance of topics about strings, which mostly include String Operations in Modern C++. We will learn to use the find() string method as well as exception handling in C++. One of the great features of C++ Builder’s VCL and FMX frameworks are forms and the form designer which makes it so easy to create and visualize the user interface for your…
When you develop an app for the Windows operating system there are a few tips that can help smooth things along. Using the best C++ compiler Windows developers have available is obviously step one, but there are a lot more very easy steps you can take to make life a lot…
Hello C++ developers. this week we have more modern C++ examples that can be compiled by any C++ IDE and compiler. If you want to dive deep into C++ programming, then the LearnCPlusPlus website is the right place for you. We keep adding more features of modern C++ and how…
To know how to get the information on the exact execution time of an operation in your Windows and cross platform apps can be useful in all sorts of circumstances. For example, it can be necessary when you need to show users the time spent on the execution of a long operation (by the way, in such a situation, high accuracy is rarely required). Or you may need to know the exact time needed for…
