Lambda Expressions allow users to write an inline expression that can be used for short snippets of code in your C++ app which are not going to be reused and don’t require naming. The Lambda Expression construct is introduced in C++ 11 and further developed in the C++17 and C++20 standards. Because of its syntax and definition with [ ] and ( ) and { }, sometimes it is hard to understand or…
How can I read a text file in a C++ app? How can I write to a text file in C++? How can I append to a text file in C++? How can I use open() method for the ifstream? How can I use open() method for the ofstream? How can I use open() method for the fstream? What is the syntax…
Do you know why we use Command Prompt or Power Shell? Can we use Windows DOS Commands in a C++ app and in other operating systems? In this post, we will explain how you can run Windows DOS commands in C++.
Apple DOS was the first family of Disk Operating Systems (DOS) for…
C++ Builder is a great IDE which comes with the FireMonkey UI framework. While Firemonkey is a powerful multi-platform UI framework which lets you create apps which work on desktop as well as mobile phones and tablets you can also use it to add many shape types to your C++ app on Windows.
TShape is the ancestor class to most other classes defined in the Objects unit. It defines the common…
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…
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…
Strings are objects that represent sequences of alphanumeric characters. The standardstringclass provides support for such objects with an interface similar to that of an array of bytes. Strings specifically designed to operate with strings of single-byte characters.
In C programming language ASCII codes are used as in char arrays to store texts in ASCII mode. You can use char…
How can we use Time in our C++ App? How can we obtain local time or UTC time? How can we get each individual property of the clock (hours, mins, seconds)?
When we write programs, it’s very common to come across two important parameters, which are Date and Time…
How can we use Date in a C++ App?
In programming we have two important parameters that we frequently use – the Date and Time properties. The Date and Time property is obtained from a timer or time module which is a physical device on the hardware you are using. For…
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 use destructors? In this post, we will try to explain how to use a Typical Destructor in Classes with given examples.
What…
