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

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

In C++, 'new' is an operator that allocates memory and calls the constructor, while 'malloc' is a function that only allocates memory.

Can you explain why using 'new' is generally preferred over 'malloc'?

Sure! 'new' provides type safety and initializes objects, whereas 'malloc' returns a void pointer and does not initialize.

What happens if I forget to delete memory allocated with 'new'?

Forgetting to delete memory allocated with 'new' leads to memory leaks, which can exhaust available memory over time.

Are there any performance differences between 'new' and 'malloc'?

Generally, 'new' can be slightly slower due to object initialization, but the difference is often negligible in most applications.
