练习：分隔符分割字符串提取每个参数及其类型

    #include "stdio.h"
    
    #define MAX 20	
    typedef unsigned char		uint8_t;
    
    typedef struct
    {
    	char *argv[MAX];
    	int argc;
    }Params_t;
    
    void buffToParams(char *buff, Params_t *params)
    {
    const char delimiters = ',';                            /*分隔符*/
     
    uint8_t buflen = 0;
    uint8_t i = 0;
    
    buflen = strlen(buff);                                  /*buff长度*/
    if (0 == buflen)
    {
        params->argc = 0;
        return;
    }
    else
    {
        params->argc = 1;
