Q: Answer-When applied to a local variable inside a C function, what does the 'static' keyword primarily do?

A static local variable retains its value between successive calls to the function in which it is declared, because it is allocated for the lifetime of the program rather than being recreated on each call. It does not delete its value after the function returns that describes an ordinary automatic variable, it does not force recalculation, it does not become globally accessible outside its scope, and its value certainly does not change randomly.
