Macro expansion output using Visual C++ 6.0

I like this option of Visual studio very much. I forgot this for long time. I have tested this option for Visual C++ 6.0 but I am 99% sure that it must be working for all new versions of visual studio.

Suppose I have simple program like

// Souce.c

#define greater(a, b) ((a) > (b) ? a : b);

int main()

{

greater(10, 20);

return 0;

}

// Source.c ends here

Now how to create a file which will show me expanded macros in this course file?

Very simple add /E and /P to project options. In the same file as that of Source.c a new file Source.i will be generated.

I am writing here contents of Source.i to understand it's contents -

# Source.i

#line 1 ...

int main()

{

((10) > (20) ? 10 : 20);;

return 0;

}

# Source.i ends here

Hope this post is of help
