        About the language part of C + + (Information Science Orsay one pass), I myself summarized some knowledge.         Because it is too basic, I won't talk about the introduction and use of the first part of the source code.         I'll start with the second chapter, sequent ...

preface **This article introduces character functions and string functions, from 0 to proficient, how to reference to how to simulate the implementation. In C language, we often operate on strings, so we can call many library functions directly. However, if we want to deeply understand C language, we need to know how to realize its princip ...

When I started to review the C language recently, I thought of getting a hand-in-hand development tool. I remembered my painful experience of installing Visual Studio and decided to choose a lighter VS code. However, after downloading the VS code, it can not be used directly. I need to configure the environment. Here is my personal method for c ...

This paper only discusses whether to return the object or the pointer of the object when writing algorithm problems in C + +. As we all know, C + + variables are different from java and python. C + + variables are not natural pointers, so the assignment between object type variables is much more time-consuming than java and python. For example ...

C + + language uses operators and expressions to manipulate data. Operators are symbols used to represent various operations in programs. The high-level language uses a method similar to mathematical calculation to represent various operations, such as y = x + 10; Where y and x represent variables and = and + represent operators. An expression ...
