Modern life has been impacted immensely by computers. Computers have penetrated every aspect of oursociety, either for better or for worse. From supermarket scanners calculating our shopping transactionswhile keeping store inventory; robots that handle highly specialized tasks or even simple human tasks,computers do much more than just computing. But where did all this technology come from and whereis it heading? Does the future look promising or should we worry about computers taking over theworld? Or are they just a necessary evil? Provide three references with your answer.

Demonstrate an understanding of the Big Five by managing deep copies, move semantics, and resource cleanup. 3. Explore the performance trade-offs between heap and stack allocation. Task Description: Part 1: Custom Vector Implementation 1. Create a Vector class that manages a dynamically allocated array. 。 Member Variables: ° T✶ data; // Dynamically allocated array for storage. std::size_t size; // Number of elements currently in the vector. std::size_t capacity; // Maximum number of elements before reallocation is required. 2. Implement the following core member functions: Default Constructor: Initialize an empty vector with no allocated storage. 。 Destructor: Free any dynamically allocated memory. 。 Copy Constructor: Perform a deep copy of the data array. 。 Copy Assignment Operator: Free existing resources and perform a deep copy.
