i'd start with c's own preprocessor and go from there:

cfp:~ > cat a.c
/* comment be gone */
main(){ printf("%i\n", (int)(0.55 * 100)); }


cfp:~ > cpp a.c
# 1 "a.c"
# 1 "<built-in>"
# 1 "<command line>"
# 1 "a.c"

main(){ printf("%i\n", (int)(0.55 * 100)); }


cfp:~ > cpp -P a.c
main(){ printf("%i\n", (int)(0.55 * 100)); }

it already knows how to strip comments.
