Hi,
The line is wrong in syntax.
R u trying to define the function get_value()
If yes then what get_rom means?

I guess u are trying to declare 2 functions get_value, get_rom in same line.
Then break it into 2 different lines
int get_value(void);
int get_rom(void);

To Enocde code tags use the # menu in the window.

It's supposed to be a function that converts roman numerals to their hindu arabic value (or is it the other way around). By the way, I tried separating them into two declarations and I still got the same error

I actually have a school project: Write a program that will allow the user to enter an Arabic number or a Roman number and then your program will convert it to the opposite (Arabic or Roman).

So you're supposed to write a function (according to your assignment) and all you do is roam the internet, dig up a piece of crappy code (which you don't understand) and expect us to do your work?

One hint: that code is not just syntactically incorrect, logically it can't convert roman numbers either. Maybe just a single roman digit; throw it away and start writing yourself.

kind regards,

Jos

Someone's in a bad mood.. that's not really what i'm here for though, i was only asking why there was a declaration syntax error in the code.. i know that was for a single roman numeral only code, the error was all i was asking about and how to somehow correct it

The compiler is complaining because of the ;. By putting semi-colon there you are declaring (as oposed to defining) a function. For reference, google C++ FAQ lite.
Why it doesn't complain about an invalid character right behind get_value(void) is a mystery.

int get_value(void), get_rom(void);
{ ...
Just what are you trying to do here?
If you want to define a function named get_rom, you should replace all this with

int get_rom() // note the absense of ;
{ ...

Oh and, don't return from a function with void return type.

Good for you; don't you think it's time to show us what you have done (just a bit of courtesy) so that you don't exhibit yourself as just another code beggar?

kind regards,
