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. A standardized (ECMA) language for creating Windows .NET applications and services and libraries - with a syntax similar to Java and C++.






2. true or false






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






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






5. A Class that cannot be Inherited






6. System.Char






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






8. 32 bit single precision floating point data






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






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






11. A symbol that specifies an operation to be performed on one or more variables.






12. Restricts access to a Member to the current Class and any Derived Class.






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






14. 32 bit integer data






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






16. System.Int16






17. 32 bit integer data






18. (== or !=)






19. 32 bit - unsigned integer data






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






21. Framework Class Library






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






23. 16 bit- unsigned word (U+0000 to U+ffff)






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






25. System.Int64






26. Groups classes together so that they have a unique identifier






27. Characteristics of an object. Something an object has. Provides a specific access point to data within a field






28. Command Language Runtime






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






30. 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'.






31. 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)






32. 8 bit - signed byte (-128 - 127)






33. 64 bit - unsigned integer data






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






35. Only requires one operand usually a count+1 or a count++ or a count--






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






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






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






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






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






41. (< or > or <= or >=)






42. System.UInt32






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






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






45. 16 bit - unsigned integer data (0 to 65535)






46. Allows a class to define multiple implementations of a method based on the number and types of arguments passed (Overloading).






47. Integrated Development Environment






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






49. 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






50. 128 bit fixed precision (financial)
