Question 2: What is programmable? It refers to a special keyboard class. This keyboard can not only input characters, but also modularize some professional functions and implant them into the keyboard to program key functions. The user can complete a series of operations and manipulations on the program by pressing the keys or combining the keys.
Question 3: What classes are there in programming? Class is a concept in object-oriented programming language. A class is actually a prototype, which defines variables and methods for a certain type of object. It represents the abstraction of a class of things with common characteristics in real life and is the basis of object-oriented programming. A class defines a set of objects. A class has a be-havoir (be-havior), which describes what an object can do and how to do it. They are programs and processes that can operate on this object.
A class is actually a prototype, which defines variables and methods for a certain type of object. It represents the abstraction of a class of things with common characteristics in real life and is the basis of object-oriented programming. A class is the definition of an object. It contains information about the behavior of an object, including its name, methods, properties and events. In fact, it is not an object in itself, because it does not exist in memory. When the code that references the class runs, a new instance of the class, namely the object, will be created in memory. Although there is only one class, you can create multiple objects of the same type in memory from this class. Classes communicate with the outside world through interfaces.
You can think of a class as a "theoretical" object, that is, it provides a blueprint for the object, but it does not exist in memory. Any number of objects can be created from this blueprint. All objects created from a class have the same members: properties, methods and events. However, each object is like an independent entity. For example, the property of an object can be set to a different value from other objects of the same type.
Question 4: What does the programming "%d" mean? Output the following variables in decimal form.
printf(b=%d,d=%d\n,b,d);
The idea of this statement is to output the value of variable bd in decimal mode. Similarly, %f is output as a floating-point number and %c as a character.
Question 5: What is programming? According to the format of computer language arc (such as C, C++, VB, etc. ), according to their own logic, you can write executable code, that is, programs, which can be passed by computers. Short for programming! (My own understanding)
Question 6: What does * mean in programming? You mean like.
Import java.io. *;
This means that it is not clear which class to import, that is, any class under this package is available.
Question 7: What does programming mean? Simply put, programming is the process of writing program code in programming language with the help of computer to achieve a certain purpose or solve a certain problem, and finally get the result.
Although the computer is very powerful. It can be used for you to surf the Internet, play games and manage the company's personnel relations. But without a program, it is equivalent to a pile of scrap iron and will not pay attention to the "orders" we give it. Therefore, we can only tame it in one way-program, which is also a special way for us to communicate with computers. [Edit this paragraph] Programming principle A program is an instruction that tells a computer how to perform a special task. For example, it is like guiding you to make a menu, or directing a traffic policeman (or a traffic sign) to drive all the way to the destination. Without these special instructions, the expected task will not be carried out. So is the computer. When you want a computer to do something for you, the computer itself can't actively work for us, so we have to give it instructions, and it can't and can't understand the description of things in human natural language at all, so we have to tell the computer what to do and how to do it with programs. Even the simplest tasks need instructions, such as how to get keystrokes, how to put a letter on the screen, how to save files on disk, and so on.
The computer mentioned above will not do anything on its own initiative. Therefore, we should make the computer "serve" for us through the program. And this process is made up by ourselves. Programming can be realized by using a programming language, and what the computer is required to do is described according to the grammar of this language.
The grammar we are talking about here is completely different from that in a foreign language. The grammar we are talking about here just depends on your program and makes some rules. After writing the program, special software will interpret or translate your program into a "computer language" that the computer can recognize, and then the computer can "understand" your words and do things according to your instructions. So programming is actually a process of "people making rules for computers". [Edit this paragraph] Common programming language * CSS cascading style sheets cascading style sheets

Question 8: What do you mean by AND or NOT in programming? How to express and (&; &): means yes and: for example, the value of (x>0 & amp& ampx & lt9)x must be greater than 0 and less than 9 or (||): means or, for example, the value of (x==7||x==4) x equals 7 or the value of x equals 4 is not (! ): No, if (x==0) x equals 0, then! X represents a number other than 0.
