Abstract: Code clone detection is an important area of research as reusability is a key factor in software evolution. Duplicate code degrades the design and structure of software and software qualities like readability, changeability, maintainability. Code clone increases the maintenance cost as incorrect changes in copied code may lead to more errors. In this paper we address structural code similarity detection and propose new methods to detect structural clones using structure of control statements. By structure we mean order of control statements used in the source code. We have considered two orders of control structures: (i) Sequence of control statements as it appears (ii) Execution flow of control statements. Keywords: Control statements; Control structure; Execution flow; Similarity value; Structural similarity.
1. INTRODUCTION Duplicate codes are identical or similar code fragments present in software program. Two code fragments are similar if these code segments are similar in their structure of control statements and similar control flow between control lines [1, 15]. Different types of code clones are [15] Type 1: Exact similar code fragments except white space and comments as shown in below example. Ex 1: Segment 1: if(n>0) { n=n*1; //multiply by plus 1 } else n=n*-1; // multiply by minus 1 Segment 2: if ( n > 0 ) { n = n * 1; //multiply by +1 } else n = n * -1; // multiply by -1 Type 2: Syntactic similar code fragments except change in variable, literal and function names. Ex 2: Segment 1: if (n>0) { n=n*1; //multiply by plus 1 } else n=n*-1; // multiply by minus 1 Segment 2: if ( m > 0 ) { m = m * 1; //multiply by +1 }

else m = m * -1; // multiply by -1 Type 3: Similar code fragments with slight modifications like reordering/addition/deletion of some statements from already existing or copied code fragments. Segment 1: if (n > 0) { n=n*1; //multiply by plus 1 } else n=n*-1; // multiply by minus 1 Segment 2: if (n > 0) { n=n*1; //multiply by plus 1 } else n=n*-1; // multiply by minus 1 x=5; //newly added statement In the above example a new statement x=5 is added. Type 4: Functionally similar code fragments. Below example explains recursive and non recursive way of finding factorial of n. (same program implemented in two ways). Ex: Segment 1: int i, j=1, n; for (i=1; i
