This article mainly introduces "Analysis of various programming skills of C++ language". In daily operation, I believe that many people have doubts about the analysis of various programming skills of C++ language. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "Analysis of various programming skills of C++ language". Next, please follow the editor to study!

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.

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.

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.

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.

For example, the following code:

Int k; int y; Xerox 10; / / oops!

In this case, the variable y is not initialized in advance, so x may get any value. The exception is that global variables and variables declared with static decorations are always initialized to 0. All other variables contain random values before initialization or assignment. Variable names can mix uppercase, lowercase letters, and numbers with underscores (_), but cannot contain spaces and other special characters.

Variable names must start with a letter or an underscore. Generally speaking, the variable name underscore or double underscore is not a good start. The allowed length of the variable name varies from compiler to compiler. It is absolutely safe if the variable name is kept below 32 characters. In practice, any variable name with more than 20 characters is impractical.

At this point, the study of "Analysis of various programming skills of C++ language" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
