Hello,

I've tried to compile this in CCS and got an error message:

for ( int index = 0 ; index < 128 ; index ++ )  { }

As far as I know C99 supports declaring valuables inside for loop - so I guess my compiler is configured to an earlier dialect of C...

How and where can I change this setting ?

Hello Shai,

You are right about how it should work, but for CCS you will need to declare int index outside of the for loop. I am not aware of a means to change that behavior. Is there a reason you cannot just declare it outside of the for loop?

Not a real reason - just a learning opportunity...
I know C99 supports it, so I wanted to learn how to change this setting.
