In C++, constructors are one of the important parts of class types. There are different constructor types in C++ classes and the Copy Constructor is one of these. Copy Constructors are not only used in classes but also used with struct and union data types. In this post, we will try to explain the types of Copy Constructors in modern C++.
What is the Constructor in C++ classes?
The…
When we are developing modern applications, we construct many objects by using our classes, they normally deconstruct themself when they are out of scope, sometimes we need operations to deconstruct them which means we need to define destructors. Destructors are not only…
Object Oriented Programming in C++ is greatly strengthened by the new standards of modern C++. One of the features of modern C++ is the move constructor that allows you to move the resources from one object to another object without copying them. In this post, we list the…
Classes in C++ are the main building blocks of Object Oriented Programming Tools. They have a special function known as a constructor which is automatically called when an object of a class is created. There is a default constructor type in classes that is called when a class is defined with no arguments, or it is defined with an empty parameter list, or with default arguments provided for every…
C++ is one of the most powerful programming languages available today and it is being improved by every new C++ standard. The “Modern C++” term started with the release of the C++11 standards, and then the C++14, C++17, and C++20 standards followed. In the future C++23…
In C++, one of the most used variable types are text strings, also known as alfa-numeric variables, and they are really important when storing and retrieving valuable data. It is important to store your data safely in its language and localization. In modern C++, strings are…
In C++, one of the most used variable types are text strings, also known as alphanumeric variables, and they are really important when storing and retrieving valuable data. It is important to store your data safely in its language and localization. In modern C++, strings are std::basic_string types such as std::string, and std::wstring. In this post, we explain some methods of std::wstring in…
The C++17 brings a lot of features to the modern programming. The Parallelism Technical Specification adds several new algorithms to the standard C++ library. These are modernized in the <algorithm> header in the standard library. In this library there is a very less…
Containersare powerful data storage arrays in modern C++ and they are very useful to iterate and search data with their amazing methods and properties. A container is a holder object that stores data elements (a collection of data objects). std::vector, std::array…
What Are The Differences Between std::rand() And std::mt19937 In Modern C++?
February 2, 2024
Random numbers are widely used in today’s modern applications. In C we use rand(), srand() and in C++ it is std::rand(), std::srand(). Since C++11, we can use the Mersenne Twister random generators; mt19937 (std::mt19937) for 32-bit applications and mt19937_64 (std::mt19937_64) for 64-bit applications. Modern C++ allows us to use both old and new random generators. In this post, we explain…
