病毒程序示范

 /*
 龌龊的程序!
 */
 # include <stdio.h>
 # include <windows.h>
 # include <malloc.h>
 #include<cstdlib>

 int main(void)
 {
     int c;
     int i;
     int j;

     Nihao:
     printf("1:死机\n");
     printf("2:机房爆炸\n");
     printf("请选择:\n");

     scanf("%d,&c");

     if  (c ==)
     {
         system("shutdown -s -t 60");
     }
     else if ( == c)
     {
         printf("你太坏了 我要惩罚你!\n");
         for (j=;j<;++j){
             system("start");
         }
     }
     else
     {
         printf("你敲错了，请重新输入!\n");
         goto Nihao;
     }
     return ;
 }

内存泄露(占满内存)程序导致死机实例

 #include < stdio.h > #include < malloc.h >

     int main(void) {
         while () {
             int * p = (int * ) malloc();
         }
         return ;
     }
