One.#define是C语言中提供的宏定义命令, the main purpose is to provide programmers with certain convenience in programming, and to a certain extent, improve the efficiency of the program, but students often do not understand the nature of the command in learning, always create some confusion here, in the programming of the misuse of the command, To make the program run inconsistent with the intended purpose, or to read the program written by others, the results of the operation to understand the error, which

As an abstract way of computer code, functions play a very important role in Python. Today we introduce the definition of Python functions, the introduction of parameters, and how to invoke them. Where the function parameters are passed in in this section is the key content.

If the first part of the function can be written as: extern int fun (int a, int b); In this way, the function fun can be invoked for other files. If extern is omitted when defini

Recently, when I was working on a project, I found that some features close to the underlying operating system were not powerful, and many third-party things were used in the project, A large part of my work is dealing with hardware and I think it is necessary to review c ++ (abandon "she" for three years). I think it is better to return to it! This trip records the beauty I have lost! Don't talk nonsense. Write it! Concept Review: "Declaration" and "Definit
