So, based on those errors, I suggest you repost this in the "begginners" section, where those who answer will understand you, and I, I won't lie to you, I just don't have the patiense. Sorry.
PS: You shoual also read this page's tutorial: http://www.cplusplus.com/doc/tutorial/

Errors:

1) Use EOF to check the end of file.

2) Use strcmp for comparing strings.

Ans what does this mean??

" replace each vowel with a corresponding number".

Does it mean the ASCII value??

Does it mean the ASCII value??

No!
f=1,g=2,k=3,p=4,h=5

f, g, p and h are for a, e, i and u, respectivly
