Compare Malloc/free and New/delete

?? When it comes to memory allocation, it is common to use malloc with Free.malloc and free as the standard library function for C++/C, New/delete is the C + + operator. They can all be used to request dynamic memory and free memory.

?? For objects of non-intrinsic data types, light Malloc/free cannot meet the requirements of dynamic objects. Objects are automatically executed when they are created, and the object executes the destructor automatically before it dies. Because Malloc/free is a library function and not an operator, the task of executing constructors and destructors cannot be imposed on malloc/free, not within the control of the compiler.

?? Therefore, C + + requires an operator new that can perform dynamic memory allocation and initialization, and an operator delete that can perform cleanup and freeing of memory work.
