The new keyword in programming languages like C++ and Java allocates memory on the heap for an object or data structure. When new is called, it requests a block of memory sufficient to hold the specified type, initializes that memory (if applicable), and returns a pointer or reference to the newly allocated memory. This memory remains allocated until it is explicitly deallocated using delete in C++ or is automatically reclaimed by the garbage collector in languages like Java. Proper memory management is crucial to avoid memory leaks and ensure efficient use of resources.
