Memory usage is really important in C and C++ programming. In the C language malloc, calloc, realloc functions comes from the <alloc.h> header and C++ language allows you to use malloc in C++ also calloc and realloc too. These memory allocations are fairly old and mostly used in C and require great caution if you use them in C++. In modern C++ we should use modern ways of C++ like std::vector…
In all programs, not just in C programming, all data and operations during runtime are stored in the memory of our computers, including IoT or other microdevices. This memory is generally a RAM (Random Access Memory) that allows data items to be read or written in almost the…
In computers, all data and operations during runtime are stored in the memory of our computers, IoTs, or in other microdevices. This memory is generally a RAM (Random Access Memory) that allows data items to be read or written in almost the same amount of time, irrespective…
Learn C++ With Embedded: Customizing Dynamic Memory Management in C++ by Ben Saks (CPPCon 2020) Videos
December 18, 2020
For several common programming problems, Dynamic Memory Allocation is a normal solution. New-expressions in C++ places dynamic memory through a function called operator new. However, too many resource-stricted systems fully ignore the use of new-expressions for customization, which is unfortunate because it has been developed for such purposes. This talk demonstrates how tailored dynamic memory…
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…
The C++17 standard came with a lot of great features and std::optional was one of the main features of today’s modern C++. std::optional<T> is a class template that is defined in the <optional> header and represents either a T value or no value. In this post…
When Is The CMath Mathematical Special Functions Header Used in Modern C++?
December 1, 2023
The math library <math.h> in C language is designed to be used in mathematical operations. From the first C language to the latest C++ Builder 12, there have been many changes and improvements in both hardware and software. We were able to use this math.h library in C++ applications. After the C++17 standard, this library is modernized in the cmath library, Functions are declared…
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…
In the last 40 years C++ has earned, and maintained, a reputation as one of the most efficient programming languages. C++ is still hugely popular, often in the top 3 of any lists of popular programming languages and is used widely across a wide array of operating systems.
C and C++ are arguably the most powerful programming languages that can be used to develop native C++ iOS apps for the ARM based Apple mobile devices. Most C++ compilers support the C language, that means you can code in C language in a C++ IDE.
C and C++ have many pre-defined functions, and libraries which make writing modern, robust C++ a breeze. Using a fast and…
