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. 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.






2. Windows Presentation Foundation






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






4. System.UInt64






5. A type of statement that produces a value that might be tested or assigned to a variable.






6. 32 bit - unsigned integer data






7. 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.






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






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






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






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






12. Allows the definition of a Class to span multiple files (within the same Project)






13. System.SByte






14. Encapsulation is the process of providing access to an object only through it's messages while keeping the details private. Encapsulation controls the use of a class.






15. Series of instructions which tell a computer what to do.






16. 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'.






17. Code which implements GUI (graphical User Interface).






18. Just-in-time compilation






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






20. When a sub class passes down all the behaviours of the original parent class






21. Documentation text embedded within code which is not to be run as code. Two types single and multiple: single // multiline / insert comment here /






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






23. true or false






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






25. 8 bit - unsigned byte (0 - 255)






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






27. A combination of language identifiers and data and operators and expressions that constitute a single line of syntactically correct & executable code.






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






29. The process of compiling IL source into CPU-native code for execution.






30. true or false






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






32. 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.






33. System.UInt16






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






35. Symbols which transform and combine expressions






36. Integrated Development Environment






37. Word that stores a value. Storage location that holds a value. Type and name of variable must be declared in a statement. Must be explicitly declared before use. Uses CamelCase notation.






38. System.Int16






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






40. System.Decimal






41. 16 bit - signed integer data (-32768 to 32767)






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






43. (== or !=)






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






45. Command Language Runtime






46. 64 bit - unsigned integer data






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






48. System.Char






49. System.Int64






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