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. Compilation of classes. In C# Usually ends in .dll or .exe






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






3. Restricts access to a Member to the current Class.






4. Represents date and time data with a 100 ns resolution






5. The CLR tool used for just-in-time compilation which converts IL code to CPU specific code.






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






7. Something that has a different number of parameters to it's predecessor






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






9. System.UInt32






10. Always runs left to right on all arithmetic operators. Parenthesis (or brackets () ) override precedence flow.






11. Access is limited to the current Assembly and Derived Types






12. count = count+1 or count++ or count__. Both count variables are Unary Operators






13. A Class from which other classes can inherit characteristics.






14. The process of hiding and restricting access to the implementation details of a data structure.






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






16. System.Decimal






17. Field whose value can never change. Declared with 'const' keyword






18. An abstract container used to hold a logically related group of data and functionality (e.g. System.* or System.Lynq or System.Windows etc.).






19. The output produced by the C# Compiler - typically a .dll or .exe. Produced by a Project in Visual Studio






20. System.Byte






21. Rules defining or outlining the format and construction of statements. Semantics is what statements actually DO Syntax are RULES for how to lay statements out. Example syntax rule; All statements must end in a semicolon.






22. A Class that inherits characteristics from another Class.






23. 32 bit - unsigned integer data






24. 8 bit - unsigned byte (0 - 255)






25. A Class that can only have Static Members






26. Indicates that the Method can be overridden.






27. 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.






28. Microsoft's generic software framework for application development.






29. Symbols which transform and combine expressions






30. The four major concepts of Object Oriented Programming: Abstraction - Encapsulation - ___________ - Polymorphism






31. 64 bit double precision floating point data






32. 16 bit- unsigned word (U+0000 to U+ffff)






33. (= or += or -= or = or /=)






34. 32 bit single precision floating point data






35. true or false






36. 64 bit - unsigned integer data






37. Sits behind GUI (Graphical User Interface) and provides event listeners






38. Specifies that a Class cannot be instantiated but can only be used as the Base Class from which other Classes are derived.






39. (< or > or <= or >=)






40. Something an object can do. A named sequence of events. Should always have a meaningful name eg calculateIncomeTax.






41. Used to display text that end user does not need to edit.






42. Command Language Runtime






43. 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






44. 32 bit integer data






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






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






47. 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.






48. Box which can be typed into at runtime. Can display large amounts of scrollable text for the user. To create a scrollable one in Visual Studio set the multiline property to 'TRUE' and the Scrollbars property to 'VERTICAL'.






49. An instance of a class that exists at run-time and is typically referenced via a variable name.






50. Calculation whose result is either true or false but cannot be both E.g. == Equal to. != Not Equal too. < Less than. <= Less than of equal to. > Greater than. >= Greaten than or equal to. && AND (Conditional) ->|| OR (Conditional)
