C++ Dynamic Memory Allocation: Basic Usage of new and delete

C++ dynamic memory allocation is used to flexibly manage memory at runtime, addressing the shortcomings of static allocation (where size is determined at compile time). The core distinction lies between the heap (manually managed) and the stack (automatically managed). Memory allocation is performed using the `new` operator: for a single object, use `new Type`; for an array, use `new Type[size]`. Memory deallocation is done with `delete` for single objects and `delete[]` for arrays to prevent memory leaks. Key considerations include: strictly matching `delete`/`delete[]` usage, avoiding double deallocation, and ensuring all allocated memory is eventually released. Proper use allows efficient memory utilization, but adherence to the allocation-release correspondence rules is critical to avoid program crashes or memory leaks caused by errors.
