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. System.Int16






2. A Class from which other classes can inherit characteristics.






3. System.UInt64






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






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






6. System.Int64






7. System.UInt32






8. (== or !=)






9. 8 bit - unsigned byte (0 - 255)






10. Framework Class Library






11. 32 bit - unsigned integer data






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






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






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






15. The .NET run-time environment that enables code to be compiled and executed.






16. Just-in-time compilation






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






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






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






20. A Class that can only have Static Members






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






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






23. System.SByte






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






25. 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.






26. 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






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






28. 64 bit integer data






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






30. 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.






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






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






33. 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.






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






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






36. 64 bit integer data






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






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






39. 32 bit integer data






40. A Class that cannot be Inherited






41. Syntax of a C# Method






42. 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.






43. The C# directive required to bring a namespace into scope. Eliminates the need to fully qualify a Type.






44. Extra information within a method






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






46. Allows a Method to be defined in a separate file (within the same Project). If no definition is found the compiler excludes the Method as an optimization.






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






48. Access is limited to the current Assembly






49. 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






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