How do I implement arbitrary arithmetic precision in C Programming Language. By using only standard library.

hey i mean with BY USING ONLY STANDARD LIBRARY is that use only header files those are available. Don't use any additional liraries.

• There are better ways for implementing the fillArray function (i.e. avoiding the 'duplicates' extraction).
• Messing up with the loop index is a very inelegant practice.
• printArray really should be called sortArray.
