C# Encapsulation Example Following is the example of defining an encapsulated class in c# programming language. using System; using System.Text; namespace Tutlane { class User { private string location; private string name; public string Location { get { return location; } set { location = value; } } public string Name { get { return name; } set { name = value; } } } class Program { static void Main(string[] args) { User u = new User(); // set accessor will invoke u.Name = "Suresh Dasari"; // set accessor will invoke u.Location = "Hyderabad"; // get accessor will invoke Console.WriteLine("Name: " + u.Name); // get accessor will invoke Console.WriteLine("Location: " + u.Location); Console.WriteLine("\nPress Enter Key to Exit.."); Console.ReadLine(); } } } As you can see from the example above, we used properties to specify the fields in the enclosed class, and we can change the values of the fields by using the get and set accessors of properties. 1.

Student Name: 8) Consider the following ciass definitions. public class LibraryID{ private String name; // Person's name private int ID; // Person's library ID # private ArrayList Books; // Loaned books public LibraryID (String n, int num) { name = n; ID = num; Books = new ArrayList(); } public int getID () { return ID; } public String getName() { return name; } /* CheckOut () and ReturnBook () methods not shown */ Complete the following override method, contained in the LibraryID class. Two LibraryID's are considered the same if their ID numbers are the same. public boolean equals (Object other) { if (other == null){ return false;} LibraryID o = (LibraryID) other; 9) Assuming the code written in 8 is correct, write the call to compare LibraryID one and two inside the if statement.

It has the following signature: void SortByPrice(std::vector<Snack>& list_ref, bool asc). This function should sort the vector list_ref based on the price_ of the Snacks. The sorting should be done in the following order: Ascending if asc is true Descending if asc is false. In both cases if variables have the same value for price_, the sorting should be done based on the name_ in ascending order.

Term by CodeChum Admin (JAVA CODE) Construct a class called Term. It is going to represent a term in polynomial expression. It has an integer coefficient and an exponent. In this case, there is only 1 independent variable that is 'x'. There should be two operations for the Term: public Term times(Term t) - multiplies the term with another term and returns the result public String toString() - prints the coefficient followed by "x^" and appended by the exponent. But with the following additional rules: if the coefficient is 1, then it is not printed. if the exponent is 1, then it is not printed ( the caret is not printed as well) if the exponent is 0, then only the coefficient is printed. Input The first line contains the coefficient and the exponent of the first term. The second line contains the coefficient and the exponent of the second term. 1·1 4·3 Output Display the resulting product for each of the test case. 4x^4
