Containers are powerful data storage arrays in modern C++ and they are very useful to iterate and search data with their amazing methods and properties. TheC++ Standardslibrary defines 4 container types. In this post, we explain containers in modern C++.
What is a container in modern C++?

Sometimes we want to preserve the string format especially when we use string in a string with /”. In C++14 and above, there is a std::quoted template that allows handling strings safely where they may contain spaces and special characters and it keeps their formatting…
The auto keyword arrives with the new features of the C++11 and the standards above. In C++14, there is a new decltype that is used with auto keyword. In modern C++, the decltype(auto) type-specifier deduces return types while keeping their references and cv-qualifiers…
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…
