Hi,
I'm looking for a tool that can compare codes in two different programs. Actually, students in my organization often copy/paste assignments which are mostly in C/C++. Some of them are clever enough to rearrange the code sequence and change the variable names. Thats what I want to catch. I do remember a former colleague mentioning about such a tool, which could compare two codes by analyzing their CDFG graphs, but my memory fails me. Please give your suggestions.
