For each of the following statements, please: Explain the statement in 5 or more sentences. And Create a code experiment to demonstrate our understanding Please remember to submit our code and document our experiment in our assignment report. 1. Deleting the same memory twice: This error can happen when two pointers address the same dynamically allocated object. If delete is applied to one of the pointers, then the object's memory is returned to the Free-store. If we subsequently delete the second pointer, then the Free-store may be corrupted. Use smart pointers... Objects that must be allocated with new, but you like to have the same lifetime as other objects/variables on the Run-time stack. Objects assigned to smart pointers will be deleted when program exits that function or block. 2. 3. Use smart pointers... Data members of classes, so when an object is deleted all the owned data is deleted as well (without any special code in the destructor) 4. Converting unique_ptr to shared_ptr is easy. Use unique ptr first and covert unique ptr to shared_ptr when needed. 5. Use weak ptr for shared ptr like pointers that can dangle

Why were most movies from the late 1890s until the early 1930s only filmed in black and white? there were only a few people who could afford the technology to produce color motion pictures back then. audiences did not want color motion pictures until later. the film used to make color motion pictures often overheated, which was a safety hazard, so it was generally not allowed. color films had to be hand-colored, frame by frame.
