int main()
{
	char arr1[] = "hello";
	char arr2[] = "world";
	char arrbuf[100] = { 0 };//全部初始化'\0'
	int index = 0;
	while (arr1[index]!= '\0')
	{
		//1、将非\0的字符添加到arrbuf
		arrbuf[index] = arr1[index];
		//2、计数器增长
		index++;
	}
	int len = sizeof(arr1) - 1;
	while (arr2[index - len] != '\0')
	{
		arrbuf[index] = arr2[index - len];
		index++;
	}
	//添加字符串结束标志
	arrbuf[index] = '\0';
	printf("%s", &arrbuf);
