I wish to (a) reinforce Chris's comment you have posted 18 and should have figured that out.


Use the advanced button and enclose you code. Use the # button.

Solution to the problem is that you missed out a : on the definition line
properties

General Note:

I believe that this forum needs a "how to debug problems" thread with the basics of how to split a problem down, how to get the compiler to work for you, rather than against you etc. The stuff that I seem to have to explain to the novices time and time again,
[particularly those that have come from interpreted languages -- because the mind set is different.]

: is not problem

PLEASE READ THE POSTS ABOVE

THAT MEANS DO NOT POST CODE UNLESS IT IS IN code BLOCKS.

Your code works fine. BUT you have the wrong g++ line (since -O is
optimize) and you really wanted -o.

Otherwise you will have to post your output and you code in CODE blocks.
