can anyone give me the C++ source code to make a control flow graph generator for C language. here i need to show any C program code as a control flow graph. that's why i want to need the source code to make control flow graph generator.

  • Just browse github. – albert Feb 19 '18 at 18:15
  • ohh..but i can not found any c++ source code to make control flow graph from c program....if you will find ,then pls give me the link.... – Shahriyar Feb 19 '18 at 19:16
  • Just a quick browse on the repositories and one can see repositories with C code (e.g. github.com/Kitware/CMake) and c++ code (e.g. github.com/gahansen/Albany). – albert Feb 19 '18 at 19:25
  • sorry, i searched almost all the respositories but i can not find anything about control flow graph in those two links........ – Shahriyar Feb 19 '18 at 19:55
  • The question suggested to me that you want to create a program to create control flow graphs and for this you need example C / C++ code. But from the comment I understand you want to have a C++ program and revert this to a C program. – albert Feb 20 '18 at 9:02

I suggest to take a look at doxygen and its possibility to generate flow graphs via graphviz visualization software. You find the sources and documentation through the provided links.

I use both libraries for code documentation and flow graph generation extensively, but myself never made customization to the source.

  • doxygen does not output the control flow, but can output a list / graph of used functions and variable. Might be that Moritz (moritz.sourceforge.net) might be something that can do something you want although its is more or less for Nassi-Schneiderman diagrams. – albert Mar 1 '18 at 18:49
