C program without main() function

Actually the main() function is embedded in the following program, however it is just like hidding it.
Try it.... It gives no errors/warnings in TurboC till compilation... In some it runs well...


#include
#define decode(s,t,u,m,p,e,d)m##s##u##t
#define begin decode(a,n,i,m,a,t,e)
int begin()
{
printf("SanuzR World...");
}

Get access to command prompt at windows welcome screen

The trick behind this is telling the system to run command prompt(cmd.exe) inspite of the Sticky function(sethc.exe).

Sticky Key: While pressing the SHIFT key for 5 times, the Sethc.exe file gets activated
This function can also be activated at the welcome screen. Hence, by replacing the Sethc.exe file
by the cmd.exe can make it possible to get command prompt at the welcome screen.


1. Go to C:\WINDOWS\System32\
2. Copy sethc.exe and past at C:\WINDOWS folder (backup copy).
3. Copy cmd.exe (C:\WINDOWS\System32) to another location (or Desktop) and remame it as sethc.exe and then copy and past it in C:\WINDOWS\System32 folder (Replace the original sethc.exe file).
4. Now restart the computer, press CTRL,ALT,DEL twice then cmd prompt will be opened.
5. From this command prompt you can get access to all programs, files and directories of the system.
5. If you want to open the start window type in "start explorer.exe" (w/o quotes) and hit ENTER.
6. If you want to roll back to the original functionality of your system (i.e. to stop this ability) just
copy the backup copy of seth.exe from the C:\WINDOWS folder and past it in C:\WINDOWS\System32 (Replace the duplicate copy )
