C语言实现按分隔符来截取字符串

问题描述：我们的系统通过Socket网络通讯往linux服务器上发送数据，服务器上接收的数据格式是以逗号隔开的字符串。我们需要将这个字符串按逗号作为分隔符来截取。

解决方法：使用C语言中的strtok()函数实现

代码实现（下面代码的功能是将字符串"now , is the time for all , good men to come to the , aid of their country"以逗号作为分隔符来截取，并将截取出的字符串打印出来）：

#include <stdio.h>#include <string.h>int main(){    char str[] = "now , is the time for all , good men to come to the , aid of their country";    char delims[] = ",";    char *result = NULL;    result = strtok( str, delims );    while( result != NULL ) {    printf( "result is \"%s\"\n", result );    result = strtok( NULL, delims );    }}

运行结果如下：

进一步：封装成实现按分隔符截取字符串的函数

#include <stdio.h>  #include <string.h>  void split(char str[],char delims[]){    char *result = NULL;     result = strtok( str, delims );      while( result != NULL ) {      printf( "result is \"%s\"\n", result );      result = strtok( NULL, delims );      }  }int main()  {      char str[] = "now , is the time for all , good men to come to the , aid of their country";      char delims[] = ",";  split(str,delims);}
