Description
All the exercises below are selected from the textbook: Thinking in C++ (volume 1). An output example is attached to each problem, of which the main goal is to give you a better sense of what a typical output looks like. So, there is no need to exactly follow the provided output. Feel free to make an adjustment accordingly. I told the TAs that we’re very flexible and fine with any reasonable output.
1. [Exercise 1 on Page 610] Create a class Counted that contains an int id and a static int count. The default constructor should begin: Counted() : id(count++). It should also print its id and that it’s being created. The destructor should print that it’s being destroyed and its id. Test your class. [35 pts]
Output example: In the constructor, cout << “An object is being created is created, id: ”<< id << endl; In the destructor, cout << “ The created object is being destroyed, id: ” << id << endl;
2. [Exercise 4 on Page 610] Create a vector< Counted*> and fill it with pointers to new Counted objects (from Exercise 1). Move through the vector and print the Counted objects, then move through again and delete each one. [30 pts]
Output example: In the constructor, cout << “An object is being created is created, id: ”<< id << endl; In the destructor, cout << “ The created object is being destroyed, id: ” << id << endl; [Optional] In the main(), print each created object’s id.
3. [Exercise-14 on Page 718] In AddingVirtuals.cpp, make all the member functions of Pet pure virtual, but provide a definition for name(). Fix Dog as necessary, using the base-class definition of name(). [35 points]
Output example: int main() {
Pet* p = new Dog(placeholder); // replace the placeholder with any name you’d like cout << p->speak(); delete p;
return 0;
}
Requirements:
* Usage of spaces, blank lines, indention, and comments for readability.
* Descriptive names of variables, functions, structs, classes, and objects (if any).
* Appropriate usage of structs, classes, and objects (if any).
Penalties:
* Zero if you have possession of a copy of online solutions or work done by someone else.
* 5-point deduction per day late
