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…
In programming, some of the most important parts are the functions that we create. They are like Lego parts that we can use in all places of the application. In modern C++ development, a function declaration is really important, and these functions gained some additional…
C++ is packed with Object Oriented Programming features, such as Classes, Objects, constructors, move constructors, destructors, etc. Since the C++11 standard, in a modern C++ compiler, one of the features is the move constructor that allows you to move the resources from…
Object-Oriented Programming (OOP) is a method of mapping real-world objects and data to computer functions and data structures. Classes and Objects are part of object-oriented methods and typically provide features such as properties and methods. In Modern C++, one of the features of OOP is copy assignment operator that is used with “operator=” to create a new object from an existing…
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…
How can I clear a string in a simple way? What kind of methods I can use in my C++ software to clear a std::string? How can I use clear() method with strings? Can I use resize() method to clear strings? How can I use erase() method to clear strings?
Modern C++…
C++ has a lot of great libraries to operate on every case, on every item. We can create or delete directories by using System Commands that we explained before in this post or we can use C++ standard library methods. In C++ Builder, we can use both of them and we can also use Disk And Directory Support Routines to create or remove directories or to get information about disks, directories, and…

In this post, you’ll get answers to these questions:
What are the Vectors in C++?How can I delete a vector member in C++?How can we use the pop_back() method in vectors?How can we use the clear() method in vectors?How can we use erase() method in vectors?
By learning…
Modern C++ uses Wide Strings and Unicode Strings to support worldwide languages. Wide Strings (std::wstring) uses wcha_tr as the character type which means they are 2-bytes chars and they are an instantiation of the basic_string class template. In C++, there are several type definitions for common character types and one of them is std::wstring types that are defined in…
