Final answer:
The possibility of increasing the size of a dynamically allocated array during runtime depends on the programming language used and its library functions, with new memory allocations typically being required.
Step-by-step explanation:
Whether the size of a dynamically allocated array can be increased during runtime can be a nuanced question, but the most appropriate answer is c) Both of the above.In programming languages like C, you cannot directly increase the size of an array once it has been allocated. If you need a larger array, you must allocate a new block of memory that is large enough, copy the contents of the original array to this new block, and then deallocate the original array. However, in other languages such as Java or Python, there are data structures available that can handle resizing for you, such as ArrayList in Java or the built-in list type in Python.In summary, while it depends on the support provided by the programming language and its library functions, new memory allocations are usually involved in increasing the size of an array at runtime.
