One of the features of a static variable inside a function
is that it retains its value between function calls. Basically 
static assigns storage on the heap rather than the stack. Most 
function data is on the stack so that when a function call 
ends all the data on the stack gets unwound and lost, but 
the heap data persists.

No that will only waste memory. temporary variables within 
functions should go on the stack so that they can be deleted.
