What are Two main Components of .Net Framework?

1:Common Language Runtime 2:Base Class Library.

Describe .Net Framework Class Library?

The Base Class Library (BCL), part of the Framework Class Library (FCL), is a library of functionality available to all languages using the .NET Framework. The BCL provides classes which encapsulate a number of common functions.

Explain the concepts of CTS and CLS(Common Language Specification)

CTS When different languages are integrated and want to communicate, it is certain that the languages have their own data types and different declaration styles. CTS define how these different variables are declared and used in run time. E.g. VB offers an Integer data type while C++ offers long data type. Using CTS, these data types are converted to System32 which itself a data type of CLS. CLS Any language(s) that intend to use the Common Language Infrastructure needs to communicate with other CLS-Compliant language. This communication is based on set of rules laid by CLS. These rules define a subset of CTS.

try { int n1,n2; n1=Convert.ToInt32(args[0]); n2=Convert.ToInt32(args[1]); int res; res=n1/n2; Console.WriteLine("res:"+res); } catch(Exception e) { Console.WriteLine(e.Message); } catch(FormatException e) { Console.WriteLine("Format Exception-"+e.Message); } If command line arguments are given as 12 r what is the output?

An Error occurs telling " A Previous catch clause already catches all exceptions" so catch block of FormatExeption should be placed first follwed by Super class Exception handler.
