Statistical analysis of C code

Question

linux

Hello!

There is a code and it is old. :)
Are there any free utilities (Win, Lin) that allow you to build pictures, graphs, analyze the code. So that you can understand what is used there and how?

Thank you.

Answer 1

If you have time in two weeks, then Understand Scitools .
I highly recommend it (this is just about pictures and graphics).
There is also Splint , but I didn’t like it, because. I have not mastered its setting.
Because Since C is a subset of C++, it is quite possible to use cppcheck .
And finally, gcc with parameters: -Wall -Wextra -Wdouble-promotion -Winit-self -Wmissing-include-dirs -Wswitch-default -Wswitch-enum -Wunused-local-typedefs -Wunused-parameter -Wuninitialized -Wno- div-by-zero -Wtrampolines -Wfloat-equal -Wtraditional -Wtraditional-conversion -Wundef -Wno-endif-labels -Wshadow -Wunsafe-loop-optimizations -Wpointer-arith -Wbad-function-cast -Wc++-compat -Wcast- qual -Wcast-align -Wwrite-strings -Wjump-misses-init -Wlogical-op -Waggregate-return -Wold-style-definition -Wmissing-prototypes -Wmissing-declarations -Wpacked -Wpacked-bitfield-compat -Wpadded -Wredundant- decls -Wnested-externs -Winline -Winvalid-pch -Wlong-long -Wvector-operation-performance -Wvla -Wvolatile-register-var -Woverlength-strings -Wunsuffixed-float-constants.
Happy refactoring and support!
