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






2. 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.






3. Syntax of a C# Method






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






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






6. 64 bit - unsigned integer data






7. Extra information within a method






8. System.UInt32






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






10. 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






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






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






13. Container for one or more Visual Studio Projects.






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






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






16. System.Int64






17. (== or !=)






18. 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.






19. 16 bit - unsigned integer data (0 to 65535)






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






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






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






23. 32 bit integer data






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






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






26. Framework Class Library






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






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






30. A Class that cannot be Inherited






31. Access is limited to the current Assembly






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






33. Un-orderd sequence of elements of the same type. Stores a fixed number of static elements of a particular type.






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






35. System.UInt16






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






37. 16 bit - signed integer data (-32768 to 32767)






38. 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)






39. 8 bit - unsigned byte (0 - 255)






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






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






42. 16 bit- unsigned word (U+0000 to U+ffff)






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






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






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






46. If (boolean expression) //true -> statement 1 statement1; else //false -> statement2 statement; //else statement2 optional






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






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






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






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