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. Allow access to types that exist in outside assemblies.






2. System.Char






3. (< or > or <= or >=)






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






5. 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






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






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






8. Un-orderd sequence of elements of the same type. Stores a fixed number of static elements of a particular type.






9. System.UInt32






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






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






12. System.Single






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






14. 32 bit single precision floating point data






15. 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.






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






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






19. (&& or || or & or |)






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






21. 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.






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






23. The four major concepts of Object Oriented Programming: Abstraction - Encapsulation - ___________ - Polymorphism






24. 16 bit - signed integer data (-32768 to 32767)






25. Symbols which transform and combine expressions






26. System.UInt64






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






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






29. System.Int64






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






31. 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)






32. 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.






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






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






35. 16 bit- unsigned word (U+0000 to U+ffff)






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






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






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






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






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






41. Text as Unicode characters






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






43. 32 bit - unsigned integer data






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






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






46. Variables defined by a class






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






48. 8 bit - signed byte (-128 - 127)






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






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