*作为c语言命令行参数时奇怪错误

Question

#include <stdio.h>
char a[100];
int main(int argc, char *argv[])
{
	char *aa=a;
	++argv;
	while(--argc){
		while(**argv){
			*aa++=*argv[0];
			++argv[0];
		}
		++argv;
		*aa++='@'; 
	}
	*aa++='\0';
	printf("%s",a); 
}

理想状态;

./a.out 123 45 *

理想状态打印;

123@45@*@

实际打印;

123@[e-mail]@a.c@

为什么同文件夹下的文件名出来了啊,而且只有*有这个毛病

一脸蒙比
