How to see expanded source code of c programs?

If for any reason , you are unable to debug a macro , then you should view the expanded code of the program to see how the macros are getting expanded.

if your source code is present in file " prg.c "  then expanded source code would be stored in " " prg.I "     .


this file can be generated by following command in command prompt.


cpp prg.c


here cpp stand for c preprocesssor. It generates the expanded source code and stores it in a file called prg.I .

you can now open this file and see expanded source code .

it gets generated in directory C:\TC\BIN
