  1. Software Clones Individual Research Presentation Presented By: AdarshKhare

  2. Outline • Introduction • Types of Clones • Root Causes for Code Clones • Strategies • Tools Suggested • Relating with 577a and 577b 1

  3. Types of Clones • Type1 • Exact copy without modifications • Type 2 • Syntactically Identical Copy ( only variable, type, or function identifiers have been changes) • Type 3 • A copy with further modifications ( statements have been changes, added, or removed) 2

  4. Root Causes • Programmers are forced to duplicate the code • Programmers reuse the copied text as a template and then customize • Time Pressure • Organizational Issues ( e.g distributed development organizations) 3

  5. Strategies • Clone Avoidance • Better to avoid them at the beginning. • Clone Removal • Can be achieved using commercial tools • Clone Detection 4

  6. Tool Suggested ( Clone Removal) • Let programmers copy and adjust, and then let tools factor out the • differences with appropriate mechanisms. –Ira Baxter, 2002 • Clone Dr 5

  7. Features of the Tool • Compares files exhaustively across whole systems • Available for many different languages like PHP 4.0 & 5.0, C,C++, C# • Supports analysis of thousands of files/millions of lines of code. 6

  8. Relating with 577a and 577b • 577a • Start gathering knowledge about the tools. • 577b • Use the tools during “Development Phase”. 7
