Thread: static array?

hey, there, i am wondering whether a static array is similar to a static variable, which hold value between subsequent calls.

Code:

void readdata(){
double workspace[3600];
...
}

and I will call the readdata() in a while loop. I am worrying that it is not efficient, since each call will allocate and deallocate the workspace[3600]. So does static array do the job?

Code:

void readdata(){
static double workspace[3600];
...
}

For reason of clarity, I want to keep the workspace[100] inside readdata() since that's the only place it is used. To pull it out and place it in the caller is not what I want.
Thanks for your reply.

If you make the thing static, it will live for the whole lifetime of the program, and each time the function is called it will have the same values as it did when the previous call ended.
