Raw pointers in C++ are low-level constructs that directly hold a memory address. They can be used for manually allocating memory, creating dynamic arrays, and passing values efficiently, among other things.

The `new` operator is used to allocate memory on the heap. The memory allocated using `new` remains available until you explicitly deallocate it using the corresponding `delete` operator.

##`delete` Operator ## `delete` Operator
The `delete` operator is used to deallocate memory that has been allocated using `new`. After memory is deallocated, it's available to be reallocated for other purposes. Failing to properly deallocate memory can lead to memory leaks. The `delete` operator is used to deallocate memory that has been allocated using `new`.

##`new[]` and `delete[]` Operators ## `new[]` and `delete[]` Operators
The `new[]` and `delete[]` operators are used for allocating and deallocating memory for an array of objects. The syntax for `new[]` and `delete[]` is very similar to that of `new` and `delete`.

In summary, raw pointers, and `new` and `delete` operators allow manual memory management in C++, providing control over allocation and deallocation. Make sure to always deallocate memory allocated with `new` or `new[]`, to avoid memory leaks in your programs.
