When the result of an expression is assigned to a temporary memory location, what is the size of memory allocated?

Default size is allocated dynamically

Explanation:

Dynamic memory allocation refers to managing system memory at runtime.

Dynamic memory allocation uses the heap space of the system memory.

When the result of an expression in a code, such as C++, is assigned to a computer's temporary memory location, the default size of the memory is used at runtime by this dynamic memory allocation.
