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






2. (< or > or <= or >=)






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






4. Text as Unicode characters






5. Block of memory for storing local variables and parameters. Automatically grows and shrinks as function is entered and excited.






6. System.UInt32






7. 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.






8. 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)






9. Command which runs repeatedly while (some) condition is true.






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






11. Extra information within a method






12. System.Decimal






13. System.Single






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






15. A Member that cannot be accessed/invoked through an Object Instance.






16. Windows Presentation Foundation






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






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






19. 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.






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






21. 32 bit integer data






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






23. 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






24. 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.






25. Symbols which transform and combine expressions






26. Command Language Runtime






27. 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.






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






29. (== or !=)






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






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






32. 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.






33. Syntax of a C# Method






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






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






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






37. The C# command line compiler which transforms C# code into IL code and produces an assembly (.dll or .exe)






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






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






40. System.UInt64






41. System.Int16






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






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






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






45. 32 bit single precision floating point data






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






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






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






49. Block of memory where objects live. Whenever a new object is created it is allowed onto the heap. Old objects are regularly deallocate from the heap to save available memory






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