That's a brief answer. How is what he is saying not true ?
A global variable can be allocated in the datasegment, meaning that the
compiler knows at comiletime what address to look for. If you allocate
things dynamically then you need to follow an extra pointer, so placing
an array in the datasegment would indeed speed up things afaik ? If not,
more than a blunt 'no' would be appreciated,
With kind regards,
