OOPS----^^^^^^^^
password is a pointer but points to nothing.
char *password = "xxxxxxxxxxxxxxxxxx"; works...

OOPS------^^^^^^^^ 
password must be allocated. With my version of initialization 
it will work (password shorter then number of x's).

OOPS---------^^^^^^^^^^^^^^^^^^^
Comparing strings doesn't work this way in C.
Should be "strcmp(gets(i), password)"
