Introduction to Template

A template in C++ programming helps to pass data type as a parameter to make the code reusable. The goal is to write a generic code that can be reused for specific types depending upon the need.

Question

You have created the following class called
Course:
public class Course {
private String code;
private long grade;
}
public String getCode() {
return code;
}
public void setCode (String code) {
this.code = code;
}
public long getGrade() {
return grade;
}
public void setGrade (long grade) (
this.grade grade;
}

In the code template below, you are given three classes: Card, CardSet, and Deck. The Card class has the attributes of value and suite, which describe the cards in a standard 52-card deck. The attribute value takes in the digits 1 to 10 as well as the standard face cards, Jack, Queen, and King. The suite attribute takes in the four suites, namely clubs, spades, hearts, and diamonds. Obviously, two cards are equal if they have the same value and suite. The CardSet class is just an ensemble of Card instances. To know which cards are in your set, just iterate through the cards via the view method. This gets a formatted list of your cards in the cards attribute. To add cards to your set, use the add_cards method. The Deck class is a child class of the CardSet class. To initialize a deck, all 52 cards from the standard deck must be added to it. For uniformity, place each suite in ascending value -- 1 to 10, then Jack, then Queen, then King. The suites must be placed in this order: clubs -…
For this assignment you will be building on your Fraction class. However, the changes will be significant, so I would recommend starting from scratch and using your previous version as a resource when appropriate. For this assignment, we will correctly handle Fractions that are negative, improper (larger numerator than denominator), or whole numbers (denominator of 1). Your class should support the following operations on Fraction objects: Construction of a Fraction from two, one, or zero integer arguments. If two arguments, they are assumed to be the numerator and denominator, just one is assumed to be a whole number, and zero arguments creates a zero Fraction. Use default parameters so that you only need a single function to implement all three of these constructors.You should check to make sure that the denominator is not set to 0. The easiest way to do this is to use an assert statement: assert(inDenominator != 0); You can put this statement at the top of your constructor. Note…
