The list of things you've done wrong is too long for me to go into detail, so here are the biggies:

1) gets is wrong
2) main should not be called recursively
3) feof is not meant to be a loop condition
4) Your constructs are very inconsistent

At least you didn't use void main. Here is the code that compiles:
