Object Oriented Programming Questions and Answers

Answer: C

Statements i and iii are true and ii is false. VB.NET is an object-oriented language implemented on the .NET Framework, and .NET is a free, cross-platform, open-source developer platform for building many kinds of applications. VB.NET is not a subset of Visual Basic 6.0: it is a later language built on .NET and rewritten in an object-oriented way, so VB6 programs do not run as VB.NET without changes. The options that mark ii as true or i as false are wrong.

Answer: D

Pascal is the non-.NET language among the options. C#, F# and J# are languages designed to run on the .NET platform, compiling to the common intermediate language that the .NET runtime executes. Pascal is the older language not designed for it. Pascal is a procedural language developed in the early 1970s, while the .NET family consists of languages such as C#, F# and Visual Basic that are compiled for the common language runtime.

Answer: A

The keyed answer is i, ii, iii and iv only: LISP, Java, C++ and Simula. Java, C++ and Simula are object-oriented languages, and Simula is regarded as the first. LISP is a multi-paradigm language that has object-oriented features through its object system (CLOS), and the key counts it. SQL is a database query language and C is a procedural language, so v and vi are not object-oriented. Many textbooks would leave out LISP, but the official key includes it.
