Answer :

Final answer:

Constructors for static objects at block scope are called once when the block is first executed, while destructors are called at the end of the program execution.

Explanation:

When discussing constructors and destructors for static objects at block scope in programming, such as in C++, they have a specific lifecycle. Constructors for static objects at block scope are called once when the block in which they are defined is executed for the first time. On the other hand, destructors for these objects are called at the end of the program execution, when the scope in which they were defined ceases to exist or when the program is terminated.

This behavior is due to the static storage duration of these objects. Their lifetime lasts for the duration of the program, which means they are created and initialized only once and destroyed only once - when the program is about to finish. This is in contrast to non-static objects, which are created and destroyed each time their scope is entered and exited.
