Function to Return a Value?

i want make function(or whatever) returns value. mean want able like:

code: [select]

if(function == value) {  //or "function() == value"??
 
}
i know set variable equal in said function, think cleaner...

the way intend make function following syntax:

code: [select]

function void() {
  value returned function generated here...
}
is possible somehow? have no formal training programming, starting better. appreciated.

thanks.
pat

just use return statement:

code: [select]

int function() {
   return 12;
}
