WebC++ provides built-in smart pointer implementations, such as std::unique_ptr, std::shared_ptr, and std::weak_ptr, which work with any data type, including arrays. The above example provides a simplified version of how smart pointers work, and there are other considerations to be aware of when working with them, which we can see with the … WebTo create something on the heap, you use new or std::malloc (or their variants). In your example, you create an object on the heap using new and assign its address to m. Objects on the heap need to be released to avoid memory leaks. If allocated using new, you need to use delete; if allocated using std::malloc, you need to use std::free.
