|marba, h0=2,h1-4,h2=8,h3=16...h(n-1)=? That's a static array 'h' of 'n-1' elements with each element assigned a predetermined, fixed value. Zero (0) is the first element. Somewhat confusing, but that's how computers count.|
h0=a,h1=b,h2=c,h3=d...h(n-1)=? is a dynamic array 'h' of 'n-1' elements with each element having the value of the variable 'a', 'b', 'c', etc. It can vary making it much more flexible.
