In C++ struct myGrades { string class; char grade; }; Declare myGrades as an array that can hold 5 sets of data and then set a class string in each position as follows: “Math” “Computers” “Science” “English” “History” and give each class a letter grade
In C++ Syntax for arrays of objects classGrades allCS[15]; //the default constructor is applied to //all elements of this array //to set the number of students in each class to 25 for (i = 0; i < 15; i++) { allCS[i].setNumStudents(25); } //Assume values in all classes.

C++ Create a class Rectangle. The class has attributes length and width, each of which defaults to 1. It has member functions that calculate the perimeter and the area of the rectangle. It has setter and getter functions for both length and width. The program should ASK THE USER TO INPUT length and width value. The set functions should verify that length and width are each floating-point numbers larger than 0.0 and less than 20.0. A sample output of your program should look like follows: length = 1.0; width = 1.0; perimeter = 4.0; area = 1.0 another example: length = 5.0; width = 4.0; perimeter = 18.0; area = 20.0 There should be three files and ONE class only. .h file contains class definition, .cpp file contains the implementation of the class in .h file and main.cpp should contain the driver code.

Example: employees [ {name: "Alice", salary: 80000}, {name: "Bob", salary: 48000 }, {name: "Carol", salary: 60000}, {name: "Dan", salary: 78000}, {name: "Ellen", salary: 100000}, console.log(employeeRaises (employees) ); // [ { name: 'Bob', salary: 44000 } ] funcation emplyeeRaises(employees){ |// Your code here} /****DO NOT MODIFY ANYTHING UNDER THIS LINE****/ try{| module.exports = employeeRaises;}catch (e) {|module.exports=null;}
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.

C++ PROGRAM STRING MANIPULATION Create a class Class1 with a string data member ‘paragraph’. Provide a constructor and getParagraph() method in the class. The constructor just assigns NULL to the data member. getParagraph() method must read a paragraph from user. The paragraph should contain at least 30 words. If there are less than 20 words, the program must ask user to enter paragraph again. Create another class Class2, and make it a friend of the class Class1. Provide a function getSubString(Class1 &obj1, int startIndex, int lastIndex) with return type string in the class Class2 which accepts an object of class Class1 (by reference) and two integers. The getSubString() function should return the substring starting from location startIndex and ending at location lastIndex. Class2 must also contain a store() function that stores the substring in a file. Print screenshot of substring stored in file as well.
