In this tutorial, you will learn in-depth about C string library function memcmp() with explanation and explicit example.memcmp() is the built-in standard library function that is defined in the string library string.h. Therefore, we should include string header library before using it....
char *strpbrk(cs,ct)return pointer to first occurrence in string cs of any character string ct, or NULL if not present. char *strstr(cs,ct)return pointer to first occurrence of string ct in cs, or NULL if not present. size_t strlen(cs)return length of cs. char *strerror(n)return ...
The <string.h> library has many functions that allow you to perform tasks on strings.A list of all string functions can be found in the table below:FunctionDescription memchr() Returns a pointer to the first occurrence of a value in a block of memory memcmp() Compares two blocks of ...
Most, if not all, of the time string manipulation can be done manually but, this makes programming complex and large. To solve this, C supports a large number of string handling functions in the standard library "string.h". Few commonly used string handling functions are discussed below: ...
#include <string.h> char *strerror(int errnum); //返回与errnum相应的错误消息的指针 因为strerror函数返回的错误消息字符串所在的空间是静态分配的,所以当前的错误消息会被下一次strerror函数调用所覆盖。 如果传给它的参数errnum是非法的,那么它会返回“Unknown error nnn”,在某些实现上也可能返回NULL指针。

Concatenating strings to other strings is likely the operation you will end using the most with a dynamic C string library. SDS provides different functions to concatenate strings to existing strings. sdssdscatlen(sdss,constvoid*t,size_tlen);sdssdscat(sdss,constchar*t); ...
