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






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






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






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






5. 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.






6. Container for one or more Visual Studio Projects.






7. 64 bit integer data






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






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






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






11. Windows Presentation Foundation






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






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






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






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






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






17. 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






18. System.Double






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






20. Symbols which transform and combine expressions






21. 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






22. 16 bit - signed integer data (-32768 to 32767)






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






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






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






26. 8 bit - signed byte (-128 - 127)






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






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






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






30. Just-in-time compilation






31. 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.






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






33. 64 bit - unsigned integer data






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






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






36. 64 bit integer data






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






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






39. 32 bit integer data






40. 32 bit single precision floating point data






41. (< or > or <= or >=)






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






43. System.Decimal






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






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






46. 128 bit fixed precision (financial)






47. true or false






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






49. System.UInt64






50. 32 bit integer data
