By replacing the global variable with a function that returns a reference to a local static variable, you can guarantee that it's initialised before anything accesses it. I’ve a bit confusion about static, auto, global and local variables Using the static keyword on a local variable changes its duration from automatic duration to static duration.

Return address of local variable from a function as static variables live till the end of the program, we can use them to return data by reference from a function in c:
Local, instance, and static variables in java differ mainly in their scope, lifetime, memory allocation, and accessibility
Local variables exist only within methods and must be explicitly initialized. Local, global and static variables all have different lifespans and scopes So what are the subtle differences between them?
