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






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






3. 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.






4. System.UInt16






5. 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






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






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






8. 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.






9. 128 bit fixed precision (financial)






10. 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.






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






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






13. System.SByte






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






15. System.Char






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






17. Just-in-time compilation






18. A Class that cannot be Inherited






19. Access is limited to the current Assembly






20. The "Type" name of data that is stored on the Heap






21. 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






22. System.Double






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






24. 32 bit integer data






25. true or false






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






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






28. A Class that inherits characteristics from another Class.






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






30. Syntax of a C# Method






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






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






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






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






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






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






38. Introduces a new class. Marked by curly brackets { }






39. A Class that cannot be instantiated.






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






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






42. Framework Class Library






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






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






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






46. System.Int32






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






48. Text as Unicode characters






49. System.Single






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