Review Multiple Choices True/False Statements Programming Write the code Bonus Question

Chapter 3: Introduction to Classes and Objects Object-oriented design & programming Classes The Syntax for a Class Variables Methods Properties set and get Events

Chapter 4: Control Statements: Part 1 The primitive data types Arithmetic operators & Precedence +, -, *, /, % The components of basic control structures The syntax of basic sequence, selection, and repetition structures in Visual C#

Chapter 5: Control Statements: Part 2 More control structures Repetition statements for, do … while statements Usage of break and continue statements Selection switch Logical operators

Chapter 6: Methods Declaration and call of methods Static methods Passing by values and references in methods ref vs. out Method overloading Method signature Basic classes/functions Math Math.Sqrt(x), Math.Floor(x), Math.Ceiling(x), … Math.PI, Math.E Random How to generate random numbers Next function

Chapter 7: Arrays Declaration and usage of arrays Index Length Initialization and reference to elements of the array Initializer list Passing arrays to methods By reference and by value Usage of the foreach statement to iterate through elements in the array

Chapter 7: Arrays (cont'd) Sorting data in arrays Array.Sort(arrayName) Search Linear search Binary search int index = Array.BinarySearch(array, value); Copying an array Array.Copy(fromArray, fromIndex, toArray, to Index, length); The declaration and usage of rectangular arrays Index int [,] array = new int [4, 6];

Chapter 8: Introduction to LINQ and Collections Write filtering statements using LINQ The usage of LINQ to query an array Sort an array using LINQ ascending (default) descending Manipulate collections (e.g., List) by LINQ Functions: Distinct() Any()

Chapter 11: Files and Streams Data Hierarchy Bits  Characters  Fields  Records  Files  Databases Create a File StreamReader fileReader = new StreamReader(fileName); StreamWriter fileWriter = new StreamWriter(fileName); Read a File string inputRecord = fileReader.ReadLine(); Write a File fileWriter.WriteLine("text"); Close a File fileReader.Close(); fileWriter.Close();

Chapter 12:Databases and LINQ Create a connection between data source and controls Display the results of the LINQ query How to update the database via controls

Good Luck! Q/A
