1. Character array Although the string type is more convenient in many aspects of processing strings, it is always at a disadvantage compared to char arrays in terms of calculation speed, and there is no string type in the C language. For subsequent data structure and algorithm courses, as well as hardware development courses, you […]

Understand the use of the null character ‘\0’ and the newline character ‘\\ ‘ in the process of copying strings by the strcpy(), sprintf(), strncpy() functions
Article directory foreword One, fgets () function Two, fgets () function instructions Three, strcpy () function Four, sprintf () function Five, strncpy () function Summarize Foreword “Understanding the null character ‘\0’ and newline character ‘\\ ‘ in C language programming” In the previous article, we have learned that the compilation system will automatically add the […]
[C language] – String and memory functions (simulate memory function strlen strcpy strcat strcmp…)
This chapter introduces some commonly used functions related to strings or some fixed memory functions, and simulates the implementation of some functions to help you understand more thoroughly. Table of Contents strlen Find the length of the string strcpy string copy strcat append string function strcmp string comparison function Find a string in the strstr […]
Simulate the strcpy function, assert, const modified pointer and the story of Liangpi boy
Well then, my dears, today I will introduce the strcpy function and its simulation, as well as the love and hatred between assert, const and Liangpi boys, come on, let’s start working! (Today’s content and stories are very interesting, I hope you will one-click three links, hehe~) 1. Know the strcpy function Not much nonsense, […]
c/c++: char* defines a constant string, strcmp() function, strcpy() function, looking for specified characters, removing spaces from strings
c/c ++: char* defines constant string, strcmp() function, strcpy() function, search for specified character, remove spaces from string Finding a job in 2022 is a super combination of education, ability and luck. In the cold winter, big factories do not recruit people. If you learn c++ at this time, As far as I know, students […]
