Just Remember  The Following Points In Order To Become A Good Programmer :

• Every Program Require & Has One & Only One 'main()' Function.
• Use Of More Than One 'main()' Is Illegal.
• Use Uniform Notation Throughout Your Code i.e. Hungarian Notation.
• Every Program [ Executable ] Statement Should End With A Semi-Colon.
• All Variables Must Be Declared With Thier Data Types Before They Are Used.
• Make Sure You Include Standard Header Files @ Start Of Program.
• When Braces Are Used To Group The Statements, Make Sure That The Opening Brace Has A Corresponding Closing Brace.
• A Comment Can Be Inserted Almost Anywhere A Space Can Appear. Use Of Appr. Comments In Proper Places Increases Readability & Understandability Of The Program & Helps User In Debugging & Testing.
