Answer 1

正如 Mehrdad 在 this question: 中所说的那样

malloc allocates uninitialized memory. The allocated memory has to be released with free.

new initializes the allocated memory by calling the constructor (if it's an object). Memory allocated with new should be released with delete (which in turn calls the destructor). It does not need you to manually specify the size you need and cast it to the appropriate type. Thus, it's more modern and less prone to errors.

NOTE:- new is an operator, malloc is a function
