[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 […]
Improving internal strength simulation implementation library function strlen/strncpy/strcmp/strcat/strstr/memcpy/memmove
strlen strncpy strcmp strcat strstr memcpy memmove strlen The function of the strlen function is to find the first element of the string and start to calculate the length of the string until ‘\0’, but the length of \0 will not be calculated #include<stdio.h> size_t Strlen(const char* src) { size_t count = 0; while (*src […]
The strcmp and strncmp functions of the standard C library (comparing two C-style strings, comparing the first n characters of the two strings)
Foreword If you want to study the strcmp and strncmp functions in the standard C library in depth, you still need to read the help documents in the Linux system by yourself. Specific input command: man 3 strcmp/strncmp You can view the complete information. strcmp function The strcmp function is a function in the standard […]
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 […]

String processing functions (strcpy strcat strcmp strlen)
1. String copy function strcpy Header file: string.h Function prototype: char * strcpy( char * dest, const char * src ) Call format: strcpy(dest,src) Function: string copy Parameters: src is the starting address of the source string, dest is the starting address of the target string Return value: the starting address of the target string […]
Self-realization of strlen, strcpy, strcat, strcmp, strstr functions in C language
Independent implementation of C language strlen, strcpy, strcat, strcmp, strstr functions: Self-realization: Independent implementation of strlen, strcpy, strcat, strcmp, strstr functions in C language: 1. strlen 2. strcpy 3. strcat 4. strcmp 5. strstr Note: The following library functions require the #include header file, and the #include header file is required to include the assert […]
