C++ is a great programming language to calculate engineering problems, it is one of the best for those operations. Delphi is also a super-fast compiled programming language that you can use in engineering problems. In this post we will explain how to write a C++ app to solve millions of unknowns in equations by using the Successive Over Relaxation Iteration Method. Haven’t you always wanted…
How can we convert one string to char array in Modern C++? Here are the answers with C++ software examples.
Generally, as an introduction to C++, in addition to int, float, double there is another data type, string that we use for alphanumeric variables. In C++ there are…
How can we read a formatted string in a C++ app? How can I convert a string to a stringstream ? What is string? What is std::stringstream? What are the methods that can be used to read the formatted strings? Is there a simple example on how to read a formatted string ? Is…
How can we print numbers in binary form? How can we set a bit in an integer? How we can set, clear, or toggle bits (binary digits) of a number? How can we change the nth bit of a number? In this post, we will answer these questions and use them in our own C++ software. First let’s remind ourselves where bits come from.
A brief background to CPU architecture
The construction, size…
Do you want to learn how to make your C++ app simulate physics of objects in 3D without using any 3D engine? In this post we will explain how we can simulate ball physics 2D in a simple way. Let’s assume that we look from a X-Y view, and Y is the height that means Y=0…
In 2021, If we combine C, C++, C++ Builder, Visual C++, Objective-C, Swift, GNU C/C++, and other C and C++ programming languages, C/C++ was the most used programming language according to most of the statistical web sites. In addition to these number there are more C++…
The C++ compiler creates an implicitly defined destructor. Do you want to learn about the implicitly defined destructor or what kind of methods we have that we can declare and use with the implicitly defined destructor? In this post, we will try to explain Implicitly Defined Destructor in Classes with given examples.
What is a Constructor in C++?
The Constructorin C++ is a function, a…
When you construct an object in your C++ app, sometimes you need operations to deconstruct. Destructors not only used in classes but also used with struct and union data types. Do you want to learn what is destructor or what kind of methods we have that we can declare and…
C++ Builder has a lot of great components you can use to create a C++ app and StringGrid (TStringGrid) is one of these. A StringGrid represents a grid control designed to simplify the handling of strings.
We can easily add a TStringGrid object to a form to represent…
Which activation function are the most popular? What is Logistic Function? What is difference between Logic Function and Sigmoid Function? How can I use these functions in my C++ app? Briefly, a Sigmoid Function is one of the most popular activation functions that are used in AI Technologies. A Sigmoid Function is a simple type of Logistic Function aka Logistic Curve. Let’s recap what an…
