What are the performance implications of using new vs malloc in C++?

What are the performance implications of using new vs malloc in C++?

Using 'new' in C++ generally provides better performance than 'malloc' because 'new' calls constructors and handles type safety.

Are there specific scenarios where one is preferred over the other?

Yes, 'new' is preferred for object creation in C++ due to its constructor calls, while 'malloc' is used for raw memory allocation.

What about memory management and deallocation?

For deallocation, use 'delete' with 'new' and 'free' with 'malloc'. Mixing them can lead to undefined behavior.

Can you explain the overhead associated with each?

'new' has slightly more overhead due to constructor calls, while 'malloc' is faster but lacks type safety and initialization.
