What is the difference between new and malloc in C++?

What is the difference between new and malloc in C++?

The main difference is that 'new' is an operator that allocates memory and calls the constructor, while 'malloc' is a function that only allocates memory.

Can you explain how memory allocation works with new?

Sure! When you use 'new', it allocates memory for an object and also initializes it by calling its constructor.

What about memory allocation with malloc?

'malloc' allocates a specified number of bytes but does not call any constructors, so the memory is uninitialized.

Are there any performance differences between them?

Generally, 'new' can be more efficient because it combines allocation and initialization, while 'malloc' requires separate initialization.

When should I use new instead of malloc?

You should use 'new' when working with C++ objects that require initialization, and 'malloc' is typically used in C or when you need raw memory.
