How to generate all possible outcome for if statement?

So I have this if statement and I want to make all the possible outcomes.

if (cuisine == '' && area == '' && city == '' && minprice == '' && maxprice == ''){}
if (cuisine != '' && area == '' && city == '' && minprice == '' && maxprice == ''){}
if (cuisine != '' && area != '' && city == '' && minprice == '' && maxprice == ''){}
if (cuisine != '' && area != '' && city != '' && minprice == '' && maxprice == ''){}
if (cuisine != '' && area != '' && city != '' && minprice != '' && maxprice == ''){}
if (cuisine != '' && area != '' && city != '' && minprice != '' && maxprice != ''){}

etc... etc...
