This article mainly explains "what are the advantages of C++ language". The content of the explanation is simple and clear, and it is easy to learn and understand. Now please follow the editor's train of thought slowly and deeply. Let's study and learn "what are the advantages of C++ language"?

Introduction to getting started

C++ is a powerful language that can be used to do jobs that no other language can do. However, this powerful function comes at a price. When you start using C++, you may encounter problems such as memory overflow and access invalidation, causing the program to crash. Here is the shortest space to introduce the language basis of C++. C++ language has its own monographs, and this kind of book is still very thick, so don't expect me to be able to explain it clearly in a few words. After readers have finished learning this book and using C++ Builder in normal time, * will have a better understanding of C++ language.

C++ can make the most of the advantages of object-oriented programming (OOP). OOP is not only a new term, but also has its practical meaning. It can generate reusable objects. The new term object, like the artifacts described earlier, is a software block that performs specific programming tasks (artifacts are objects, but not all objects are artifacts, which will be explained later).

The object simplifies the use of the object by displaying only the necessary parts to the user (the programmer who uses the object). All the internal mechanisms that users do not need to know are hidden behind the scenes. All of this is included in the concept of object-oriented programming. OOP can be programmed in a modular way to avoid starting from scratch every time.

C++ Builder programs are OOP-oriented because C++ Builder uses a lot of widgets. Once the widgets are generated (the ones you generate or built into C++ Builder), they can be reused in any C++ Builder program. Components can also be extended to generate new components with new functions through inheritance. Best of all, the component hides all the details of the content, allowing programmers to focus on making full use of the component.

Before C++, there was C language. C++ is based on C language, which is called "C language with classes". This C language foundation is still very important in today's C++ programs. C++ does not replace C, but complements and supports C. The rest of this chapter and the following chapters mainly introduce the part of C++ that comes from C language. In fact, the C language is introduced here, and it is only then transferred to C++ in lesson 2, "the basics of C++". Readers don't have to care about which is from C and which is from Caterpillar, because it's all in C++. It is difficult to introduce the C++ language in order because all the features we are going to introduce are cross-cutting. I prepared to introduce one piece at a time, and then piece it together. By the end of lesson 3 "Advanced C++", you will have a complete understanding of C++ language. It doesn't matter if you don't grasp a concept all of a sudden. Some concepts can only be fully understood through practice.

Variable

Let's start with variables. The variable (variable) is actually the name assigned to the memory address. After you declare a variable, you can use it to manipulate the data in memory. Here are a few examples to illustrate. The following code segments use two variables, with a description statement at the end of each statement describing what happens when the statement is executed:

Int x declared and initialized to int / variable declared as an integer variable x = 100 x now contains the value / variable declared as an integer variable x = 100 x now contains the value /'x 'now contains the value 100 x + = 50 x x' now contains the value 100 x + = 50 x x 'now contains the value 150 int y = 150 x x' now contains the value 150 x + = x x now contains the value 300 x balance

The new term variable (variable) is the memory address of the computer where a value is stored. Note that the value of x changes when the variable is manipulated, and the C++ operator for the variable will be introduced later. Warning declared and uninitialized variables contain random values. Because the memory to which the variable points has not been initialized, it is not known what value the memory address contains.

Thank you for your reading. the above is the content of "what are the advantages of C++ language". After the study of this article, I believe you have a deeper understanding of the advantages of C++ language. The specific use of the situation also needs to be verified in practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
