A local variable that is declared as causes the program to keep the variable and its latest value even when the function that declared it is through executing.

Static.

Explanation:

A local variable can be defined as an argument passed to a function or a variable that is declared within a function and as such can only be used or accessed within the function.

This ultimately implies that, a local variable is effective whilst the function or block is being executed (active).

Basically, all local variables can only be a member of either the register storage, static or auto (dynamic) categories in computer programming.

A local variable that is declared as static causes the program to keep the variable and its latest value even when the function that declared it is through executing.

Hence, the memory of a local variable that is declared as static remains for the lifetime (duration) of the whole program.
