What does declaring a variable as static inside a function in C++ imply about its storage duration?

It is created each time the function is called
It is allocated once at a fixed address in memory
It is stored on the heap
It is passed by reference automatically

The correct answer is: It is allocated once at a fixed address in memory

Declaring a variable as static inside a function in C++ means that it is allocated once at a fixed address in memory. This implies that the variable's value will persist between function calls and will not be recreated each time the function is called. The other options are incorrect because - Option A is incorrect because declaring a variable as static means it is not recreated each time the function is called, compared to non-static variables which are created each time the function is called. - Option C is incorrect because the heap is not used for storing static variables. - Option D is incorrect because passing by reference refers to a way of passing arguments to functions, and it is not related to the storage duration of variables.
