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. Command Language Runtime






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






3. 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'.






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






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






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






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






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






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






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






11. System.Single






12. 64 bit integer data






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






14. System.Int64






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






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






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






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






19. 128 bit fixed precision (financial)






20. 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)






21. 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.






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






23. The "Type" name of data that is stored on the Stack






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






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






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






27. Container for one or more Visual Studio Projects.






28. Syntax of a C# Method






29. System.Decimal






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






31. A Class that cannot be instantiated.






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






33. 64 bit integer data






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






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






36. (< or > or <= or >=)






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






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






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






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






41. Must have a data type






42. System.Double






43. true or false






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






45. true or false






46. Access is limited to the current Assembly






47. System.SByte






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






49. 64 bit double precision floating point data






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