1.Introduction to strstr #include<string.h> char* strstr(const char* str1,const char* str2); Input the array name of the parent string and the array name of the substring. The function will return a pointer of type char*. This pointer points to the address of the first element of the first substring in the parent string. So how do […]

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 […]
C language dry goods you should know (4) (strncpy, strncmp, strncat, strstr, strtok)
We know that after including the string.h header file, we can use strncpy, strncmp, strncat, strstr, strtok these library functions, let us understand them next. Table of Contents #strncpy #strncmp #strncat #strstr #strtok #Next issue preview #strncpy The function of this library function is very similar to strcpy, the difference is that Did you find […]
Implement strStr(), give you two strings haystack and needle, please find the subscript of the first occurrence of the needle string in the haystack string (the subscript starts from 0).
Title: Given two strings haystack and needle, please find the subscript of the first occurrence of the needle string in the haystack string (the subscript starts from 0). Returns -1 if needle is not part of haystack. Example 1: Input: haystack = “sadbutsad”, needle = “sad” Output: 0 Explanation: “sad” matches at subscripts 0 and […]
