Hi friends,

Today I am here to give you all the process of making an alarm clock.

 Many of us would feel the need to have an on screen alarm clock to

 remind us of our important tasks. You can add any tasks like opening

a browser or maybe your HDD [e.g.: C:]. So, today I am posting about 

making you own alarm clock. This would be very useful as you do 

not need install any softwares. 

This is very easy to make since I have provided you with the coding. 

IMPORTANT INSTRUCTIONS :

• Copy the text given below in the scrollbox.

• Make a new Text file by clicking on Start >

   All Programs > Accessories > Notepad.

• Paste the entire code in the new text document.

• Click on File > Save As > Change "Save As Type" 

  to "All Files".

• Give the file name Hit The Alarm.bat

  [N.B.: Do not forget to give the extension as .bat]

• Click on Save.

• Now double-click to Play the game.
