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. 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.






2. System.UInt16






3. 16 bit- unsigned word (U+0000 to U+ffff)






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






5. System.Int64






6. Must have a data type






7. 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






8. 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.






9. System.Char






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






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






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






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






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






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






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






17. A Class that can only have Static Members






18. Container for one or more Visual Studio Projects.






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






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






21. 128 bit fixed precision (financial)






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






23. System.Byte






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






25. Just-in-time compilation






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






27. 16 bit - signed integer data (-32768 to 32767)






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






29. 64 bit integer data






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






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






32. System.UInt64






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. Integrated Development Environment






35. System.UInt32






36. 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






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






38. 32 bit - unsigned integer data






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






40. Command Language Runtime






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






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






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






44. System.Int16






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






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






47. (< or > or <= or >=)






48. 16 bit - unsigned integer data (0 to 65535)






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






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