you declared a function with a return value of int and it takes void as its parameters.
This is basically a language problem. You may want to define a variable as your name indicates, but you should omit the '()' if you are doing so only for a default initialization. Taking it away will be fine and clear.

I'm not sure if I understand your question, but here it goes:

int var();

declares var to be a function that takes not parameters and returns an
int. It does not declare var as int-variable. If you expected var to be
a variable then you might want to search the internet for "most vexxing
parse".
