Coding error

[Anthony Stephen Ajduk]

Hi,

Can anyone help with the code below. I keep getting the error messages below and cannot work out the solution.

Regards,

Anthony

Hi!

I think that you have forgotten to write closing parenthesis } in the end. Also start() should return value.

[Carl Schreiber]

The error message tells you exactly which { misses its closing counterpart. Check your code where is surplus } and delete it.

Thank you,

It is now showing the following.

This is not mistake.

You can add return 0 in the end of start()
