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






2. true or false






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






4. System.Char






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






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






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






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






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






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






11. (== or !=)






12. Extra information within a method






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






14. 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.






15. 16 bit - unsigned integer data (0 to 65535)






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






17. System.UInt16






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






19. Framework Class Library






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






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






22. 64 bit double precision floating point data






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






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






25. Indicates that the Method can be overridden.






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






27. Container for one or more Visual Studio Projects.






28. 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.






29. A Class that cannot be instantiated.






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






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






32. 32 bit integer data






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






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






35. System.Single






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






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






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






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






40. Access is limited to the current Assembly






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






42. 64 bit - unsigned integer data






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






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






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






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






47. true or false






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






49. Text as Unicode characters






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