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 pointers, they came with C++11. The most used types of C++ smart pointer areunique_ptr, auto_ptr, shared_ptr, and weak_ptr.
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…
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 initialization is and what were the changes to it in modern C++ standards.
What is aggregate member initialization in modern…
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…
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, C++17, and C++20 standards. In C++14, lambda expressions are improved by the generalized lambda (generic lambda) or…
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…
Modern C++ has a lot of useful functions coming from C. One of them was the gets() function that we use to get string inputs and that we were able to use in C++11 or earlier. In C++14, the gets function was removed, while fgets or other input functions remain there. If you…
A programming language consists of a lot of expressions in our source code. One of elements of expressions in C++ are literals. A more specific type of literal is Integer Literals. Integer literals are primary expressions that allow values of integer types (i.e., decimal, octal, hexadecimal) to be used in expressions directly. They are further improved by the boolean literals (binary digits) in…
