两个字符串分解函数

void  StrSplit(int n, char *buf, char *buf2)
{
	int i = 0;
	static int count = 0;		/*使用静态局部变量count计数*/

	if (count == strlen(buf))
		count = 0;
	for (i = 0; i < n; i++)
	{
		buf2[i] = buf[count];
		count++;
	}
	buf2[i] = '\0'; 
	return ;
} 

/*十六进制地址转换*/
void StrChange(char *address, char *src,int num)
{
	int i;
	int n = num;
	char buf[3] = {0};

	for(i = 0; i < n; i++)
	{
		sprintf(buf, "%02x",src[i]);
		printf("%s\n",buf);
		strncat(address, buf,2);
		memset(buf, 0, sizeof(buf));
	}
	return;
}


void SubString(char *dest, char *src, int start, int end)  
{  
	int i = start;  
	if (start > strlen(src))
		return;  
	if (end > strlen(src))  
		end = strlen(src);  
	while (i < end)  
	{     
		dest[i-start] = src[i];  
		i++;  
	}  
	dest[i-start] = '\0';  
	return;  
}  

 

最近一直搞得比较简单的小程序··也就是串口接收数据的接收和解析，老感觉没什么干劲··记录下常用的两个分解字符串的函数吧，新手简单小程序···
