Control Flow Graph (CFG) is a visualized programming tool. A CFG reflects the executable flow directions of all segments within a subroutine. It also represents the real--time execu.non prooeRs of a subroutine. This paper introduces the characteristics of CFG. CFG fall"' ions,its implementation approaches and used methods are given in detail as well.
