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






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






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






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






5. 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






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






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






8. 32 bit - unsigned integer data






9. 8 bit - signed byte (-128 - 127)






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






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






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






13. 64 bit double precision floating point data






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






15. 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.






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






17. 16 bit - unsigned integer data (0 to 65535)






18. System.Int64






19. System.UInt16






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






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






22. true or false






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






24. 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)






25. Windows Presentation Foundation






26. Text as Unicode characters






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






28. System.Byte






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






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






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






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






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






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






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






36. 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.






37. System.Char






38. Indicates that the Method can be overridden.






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






40. System.Int32






41. A Class that cannot be Inherited






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






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






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






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






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






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






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






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






50. Framework Class Library
