1. The copy constructor is used for one the following scenarios: I. Initialize one object from another of the same type. II. Copy an object to pass it as argument to a function. III. Copy an object to return it from a function. Read the following program and answer questions (20 points) #include <iostream> using namespace std; class Line public: int getLength( void); Line( int len // simple constructor Line( const Line &obj) 1/ copy constructor Line (); //...

Using an appropriate definition of ListNode, design a simple linked list class called StringList with the following member functions: void add (std::string); int positionOf (std::string); bool setNodeVal(int, std::string); std::vector<std::string> getAsVector(); a default constructor a copy constructor a destructor The add() function adds a new node containing the value of the parameter to the end of the list. The positionOf() function returns the (zero-based) position in the list for the first occurrence of the parameter in the list, or -1 if...

In object-oriented programming, the object encapsulates both the data and the functions that operate on the data. True False Flag this Question Question 101 pts You must declare all data members of a class before you declare member functions. True False Flag this Question Question 111 pts You must use the private access specification for all data members of a class.

The function should have a class name CPizza that will have three constructors (default, type, and copyl, public functions to use and implement are noted for you in the starter kit, and private member variables (all which are allocated dynamically). The private member variables include the three different sizes of pizza (Large, Medium, and Small), cost, a bool delivery, name, and delivery fee. The prices of the pizzas' are $20. $15, and $10 for large, medium, and small respectively. The...

1. Create an “include guard” (all lines of code required) for a file “plane.h” 2. When you look at a constructor, how can you determine if it is THE default constructor? 3. What can a “friend” function do that other non-member functions can not do? 4. class plane { int x;} ---------------- is x public or private? 5. What kind of a search first sorts the data into ascending or descending order, then splits the data in half, searches, splits,...

What are constructors? Explain why they are needed in an object-oriented programming language. If inheritance takes place, what is the order in which the parent and child constructors are called? Can a constructor be overloaded? Can a constructor be overridden? Explain when a destructor should be declared as virtual in C+? Explain the use of the access specifiers public, protected and private in C++. Which is the default specifier?

The code should be written in C++. I included the Class used for this function. Also, please fix the main function if necessary. Description: This function de-allocates all memory allocated to INV. This will be the last function to be called (automatically by the compiler) //before the program is exited. This function also erased all data in the data file. There are other functions that add, process and alter the file; the file printed after those functions will have new...
