HTML Editing in Editor to Add a new code :

1. The codes in multiple languages are added using below tags.

   [sourcecode language="CPP"]
     // Your C++ Code
   [/sourcecode]
   
   [tabby title="Java"]
    [sourcecode language="Java"]
    // Your Java Code
   [/sourcecode]

   [/sourcecode]
   [tabbyending]
   

2. To add your code, please add appropriate tag and write code between the tags (Please note that, we need to keep existing content as it is and add our code with appropriate tags).
3. If [tabby title=”C++”] and [tabbyending] are not already present, then you need to add [tabby title=”C++”] for existing code (if existing code is in C++) and one [tabbyending] at the end.

Code Style Guidelines :

1. In the beginning of every program, please write a line to tell the purpose of program :
   filter_none

   edit
   close

   play_arrow

   link
   brightness_4
   code

   // C++ program to illustrate sum of two numbers

   chevron_right

   filter_none

2. Variables used in the code, program structure and output should match with the existing code.
3. Please add following comment at the bottom of your code.

   // This code is contributed by your_name 

4. Variable names and output of newly added code (for example Java) should be same as existing code (For example C++).
5. It is strongly recommended to refer general coding guidelines when adding code for any language.
