Somebody help me ??

Question

Assuming buf is a valid pointer, what is the problem in the code below? What would be an alternate way of implementing this that would avoid the problem?
size_t sz = buf->size();
while ( --sz >= 0 )
{
/* do something */
}

Answer 1

I assume buf is an object with a method called size. You don't need to specify the >=0 in the while condition. It get's executed until the whole statement is <=0

If that wasn't the question let me know.
