C is compiled, so none of the compile time logic is avialable at
runtime. Unlike some other languages you can't write a string in
C like "if(a==b) printf("Hi");" and have the C environment evaluate
it for you.
You can write your own interpreter. Go to my website
http://www.malcolmmclean.site11.com/www
and look at the MiniBasic webpages (below the book) to understand how 
to get started in the interpreter game.
