In order to find clone code and detect the error,a variety of clone testing technology is studied.One of the clone detection(based on PDG) is described in detail,then an example of the process are analyzed.However,compared to other techniques,this technique show a unique advantage,but it would not achieve the desired effect for function cloning.To make clone detection more detailed and precise,the formation program of dependence graph is further improved in the grammar punctuation of statements,in regulation of the meaning of the statement.
