please descript the difference with malloc of c and new of c++

In C, memory allocation is typically done using the `malloc` function, which is part of the C standard library. Here's how it works: **C - malloc()** ```c void* malloc(size_t size); ``` `malloc` allocates a block of uninitialized memory of the specified size in bytes. If successful, it returns a pointer to the allocated memory; otherwise, it returns `NULL`. The programmer is responsible for managing this memory by calling `free()` when no longer needed. **C++ - new** In C++, memory allocation is performed using the `new` keyword, which is part of the language itself. It also involves dynamic memory allocation but provides additional safety features: **C++ - new** ```cpp void* operator new(size_t size); ``` `new` does similar work as `malloc`, allocating memory and returning a pointer. However, C++ adds constructors for objects (if applicable), meaning that if you allocate an object with `new`, its constructor will be called automatically upon allocation. Additionally, C++ provides `delete` to deallocate the memory when no longer needed: ```cpp void operator delete(void* ptr); ``` **Differences:** 1. **Error handling:** C++'s `new` includes bounds checking, while `malloc` may not. This means `new` can throw exceptions if memory cannot be allocated, whereas `malloc` silently fails. 2. **Resource management:** In C, you must manually call `free` to release memory. In C++, this is handled implicitly with `delete` or `delete[]` for arrays. 3. **Memory alignment:** C++ ensures proper alignment for certain types, while `malloc` does not guarantee alignment. 4. **Object construction/destruction:** C++'s `new` supports automatic construction and destruction of objects, which is not possible with `malloc`.
