What main advantage does dynamic memory allocation provide?

Unlimited memory usage
Memory is automatically managed
Control over object lifetime
Faster execution time

The correct answer is: Control over object lifetime

Dynamic memory allocation does not provide unlimited memory usage as it can lead to memory leaks and fragmentation. Memory is also not automatically managed, as it requires explicit allocation and deallocation in order to avoid memory leaks and other issues. While it may offer some control over object lifetime, it does not directly affect the execution time of a program. Therefore, the main advantage of dynamic memory allocation is the control it provides over the lifetime of objects, ensuring that memory is only used when needed and properly released after use.
