I know I'm not participating in the C class, but I can answer some of your 
question

>eng_to_metr.c: In function `main':
>eng_to_metr.c:30: warning: char format, different type arg (arg 4)
>eng_to_metr.c:34: warning: implicit declaration of function `strcmp'
>eng_to_metr.c:36: warning: implicit declaration of function `strcpy'

lines 34 and 35 is from you not including string.h where those functions are 
declared
#include <string.h> at the beginning of your file

I *think* that you're having problems passing in a pointer to a pointer with 
&english in sscanf.  english is already a pointer because it's an array 
variable

Hope this helped,
Laura
