/* Just Compile and Run, then you will get "Insufficient number of arguments" message and press enter key.
then you will go to File menu and click Dos shell option, then you will get a prompt like C:\TC\BIN.
there you type C:\TC\BIN\filename "12" "13" press enter key. Answer will be Sum of entered numbers=25
ie "12" and "13" are arguments which are given as Command Line Arguments */
