Program Plan Intro

Find output for the given Queue

Program plan:

  • Import necessary packages.
  • Create a class “StackQu”,
    • Define the method “mystery2()” that accepts “Queue”,
      • Create the object for “Stack”.
      • Calculate the size of “Queue”.
      • Execute loop till queue size,
        • Assign the integer removed from the “Queue”.
        • Check whether the integer is even,
          • If it is true, add that integer into the “Stack”.
        • Otherwise,
          • Add that integer into the “Queue”.
      • Print the “Queue” element and then the “Stack” elements.
    • Define the method “main()”,
      • Create object for “LinkedList”.
      • Call the “add()” method of queue to add the elements “1”, “2”, “3”, “4”, “5” and “6” into the “Queue” one by one.
      • Call the method “mystery2()” with “Queue” as a parameter.

Objective: 1. Implement a custom Vector class in C++ that manages dynamic memory efficiently. 2. 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. Move Constructor: Transfer ownership of the data array…
2.68♦♦ Write code for a function with the following prototype: * Mask with least signficant n bits set to 1 * Examples: n = 6 -> 0x3F, n = 17-> 0x1FFFF * Assume 1 <= n <= w int lower_one_mask (int n); Your function should follow the bit-level integer coding rules Be careful of the case n = W.
Hi-Volt Components You are the IT manager at Hi-Voltage Components, a medium-sized firm that makes specialized circuit boards. Hi-Voltage's largest customer, Green Industries, recently installed a computerized purchasing sys- tem. If Hi-Voltage connects to the purchasing system, Green Industries will be able to submit purchase orders electronically. Although Hi-Voltage has a computerized accounting system, that system is not capable of handling EDI. Tasks 1. What options does Hi-Voltage have for developing a system to connect with Green Industries' pur- chasing system? 2. What terms or concepts describe the proposed computer-to-computer relationship between Hi-Voltage and Green Industries? why not? 3. Would Hi-Voltage's proposed new system be a transaction processing system? Why or 4. Before Hi-Voltage makes a final decision, should the company consider an ERP system? Why or why not?
