Trace Analysis Method on Iteration Construction for Programming Language

Cycle structure is important in advanced programming language.However,it is difficult to teach and comprehend for students and teachers due to jump construct and variable.So cycle structure becomes a teaching difficulty,most of students difficultly consult the right result of cycle structure.In order to deal with the question,put forward a kind of circular structure tracking analysis method,which uses chart to track loop structure and variable,sequence to describe the change rule of variable,grasping the relationship between the variables,and makes the teachers teaching and students learning synchronization.The teaching method enhances the process accuracy and efficiency for students.Through the teaching application and experimental analysis shows that this method is effective,and has achieved good teaching effect.
