C# Programming Basics

Subject : it-skills
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Something that has a different number of parameters to it's predecessor






2. The .NET run-time environment that enables code to be compiled and executed.






3. A representation of an area in the computer memory in which a value of a particular data type can be stored.






4. A Class that inherits characteristics from another Class.






5. true or false






6. The act of generalizing or thinking about an object in general terms. The act of identifying the data members and behavior of a Class.






7. 16 bit - unsigned integer data (0 to 65535)






8. Extra information within a method






9. The concept of defining subclasses of data objects that share some or all of the parent's class characteristics - enabling the reuse of code.






10. Code which signifies a carriage return. Symbolises a new line in a text box.






11. Data Type Built into C#. Built into the XML Schema. Most common are: Int - Long - Float - Double - Decimal - String - Char and Bool.






12. 64 bit integer data






13. Syntax of a C# Method






14. System.UInt64






15. Thing which gives something a value. E.g. Assignment Expression uses the '=' operator to assign a variable value such as x = y * 5






16. The member type of a Class that performs an action.






17. 8 bit - signed byte (-128 - 127)






18. Indicates that the Method can be overridden.






19. If (boolean expression) //true -> statement 1 statement1; else //false -> statement2 statement; //else statement2 optional






20. The C# directive required to bring a namespace into scope. Eliminates the need to fully qualify a Type.






21. Un-orderd sequence of elements of the same type. Stores a fixed number of static elements of a particular type.






22. 32 bit integer data






23. Four things common to all software development: _______ - Flow of Control - Identifiers & Arguments - Testing / Debugging






24. A Class that cannot be instantiated.






25. (&& or || or & or |)






26. Framework Class Library






27. Allow access to types that exist in outside assemblies.






28. Contains the class definitions that allow access to the functionality provided by .NET.






29. 16 bit- unsigned word (U+0000 to U+ffff)






30. Specifies that the Method includes no implementation and must be overridden in a deriving class - where it will get its definition. Can only be part of an Abstract Class.






31. Runs in a command prompt window rather than a GUI (graphical User Interface) one.






32. Statements are instructions describing how to run a programme. Statements declare the name of a variable. Statements are combined to create methods.






33. The result of successful compilation of source code written in any .NET targeted language - e.g. C# or Visual Basic or C++.






34. Names reserved by the compiler that coders are not allowed to use as identifiers.






35. System.Int32






36. The lowest level or fundamental data types needed for representing data.






37. Most common kind of reference type. They define objects. They must have at least one method and one field.






38. Represents the encapsulation of data and behaviors into a single unit.






39. Instance of a type created when a program runs. Can be visible or invisible. Has properties and events and methods. Properties- determine appearance. Events - trigger a response. Methods - something the object does






40. Integrated Development Environment






41. Names used to identify program elements (e.g. namespaces & classes & methods & variables). Must always start with a letter. Always case sensitive. When multiword must be presented in CamelCase. keywords are an example of an identifier.






42. Mathematical (+ or - or / or %)






43. Object Oriented Programming relies on dot.notation. Dot Notation enables public methods to be fully accessible from outside an object. Member names are separated by a dot (.). Syntax is method-defined-in-class.bject-in-runtime-of-class






44. A method that is called whenever an Object is created. The method uses the same name as the Class.






45. System.Byte






46. Implies that the programming language places severe restrictions on the intermixing that is permitted to occur - between objects or data of different types.






47. 64 bit integer data






48. Keyword which exposes members to other classes OR Identifier which makes program elements public






49. Allows a Method to be defined in a separate file (within the same Project). If no definition is found the compiler excludes the Method as an optimization.






50. System.Double
