I don't have time to tell you how to fix your code at the moment, but when posting code you should put a / in the last [/code] box.

As I recall, in C++ you declare a variable explicitly as a type. Take as an example your function:
CODE
void fst(string ans[3])

There's only one variable, an array of type string. Try calling it with only the array variable. Replace your erroring line with something like thus:
CODE
fst(ans[3]);

Yes, the comma after "string" will surely make that into two arguments.

The input parameter for your fst function needs to be an array of string's, not just one individual string, which is what you get from the subscript next to the array name. (and since the array is indexed 0-2, then you're actually accessing something which is out-of-bounds anyway)

You probably want to make this line
fst(string, ans[3]);//this is the error line
look like this
fst( ans );
