static constants

[Bill Woessner]

Is there any benefit to be gained from declaring a local constant static?
The only scenario I can envision is if the constant were a large,
complicated object or perhaps a large array. Making it static would
ensure it's only allocated once. The flip side, of course, is that it
hangs around until your program terminates.

Sorry if this is an old topic. I've thought about it for a while and
haven't come to any resolution. Thanks.

"const" makes it not to be changed.
"static" limits access to the variable only from within the local scope.
"static" will initialize at the first time entering the scope and skip the
line of code after that - this do save a little bit of execution time though
not much.

No it doesn't.
