The C++14 standard (and later), brings a lot of useful smart pointers and improvements on them. They help us to avoid the mistake of incorrectly freeing the memory addressed by pointers. In modern C++, we have the new and delete operators that are used to allocate and free objects from memory, and in this post, we explain how to use new and delete operators.
Can we use new and delete elisions…
C++ is a very precise programming language that allows you to use memory operations in a wide variety of ways. Mastering efficient memory handling will improve your app performance at run time and can result in faster applications that have optimal memory usage. One of the…
Allocating memory and freeing it safely is hard if you are programming a very big application. In Modern C++ there are smart pointers that help avoid the mistake of incorrectly freeing the memory addressed by pointers. Smart pointers make it easier to define and manage…
In C++, the constexpr specifier is used to declare a function or variable to evaluate the value of at compile time, which speeds up code during runtime. This useful property had some restrictions in C++11, these are relaxed in C++14 and this feature is known asRelaxed Constexpr Restrictions. In this post, we explain what are the relaxed constexpr restrictions in modern C++.
What is the…
The template is one of the great features of modern C++. They are a simple and very powerful statement in C++ that defines the operations of a class or function. The C++14 standard and above allows the creation of variables that are templated. In this article, we will…
The Aggregate Member Initialization is one of the features of C++. This feature is improved and modernized with C++11, C++14 and C++20. With this feature, objects can initialize an aggregate member from braced-init-list. In this post, we explain what the aggregate member…
C++11 allowed lambda functions to deduce the return type based on the type of the expression given to the return statement. The C++14 standard provides return type deduction in all functions, templates, and lambdas. C++14 allows return type deduction for functions that are not of the form return expressions. In this post, we explain the auto keyword, what is an auto type deduction, and how we…
The Lambda Expression construct is introduced in C++ 11 and further developed in the C++14, C++17, and C++20 standards. C++14 standard introduced thegeneralized lambda capture (init capture) that allows you to specify generalized captures, it allows to use move capture…
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++14…
What Does Deprecated Mean And How To Use Deprecated Attribute In C++?
September 15, 2023
C++ is very strong in every aspect of modern programming and evolves and refines itself even further with the release of each new C++ standard. While there are many new additions there are some features that are found not useful or dangerous in programming, thus the community offers its deprecation in the next standard and then it is generally removed in the following standard. C++14 came with a…
