CTS Common Type System| Components of Dot Net framework

LAKS Tutorials
Most Important Component of the Dot net frame work is CTS (Common Type System). In Language specification specifies the syntactical rules. where as Cts verifies the data type.

Common Type System

In Manged code execution Dot net supports the 61 Programming languages among all these programming languages has its own data type system.
Every programming language has its own data type system, one programming language can not understand the other programming language data types system.But all the programming language data types are commonly executed by CLR. This is because of the CLR does not conatin any programming language data type or can't understand the ant other programming language data types rather CLR has its own data type system.
At the time of compilation all programming languages data types are converted CLR's data type language compiler. So CLR understand its data types.
Data type system of CLR is common to the programming languages supported by .net . This system is known as "Common Type System".
Commont Type System of CLR is Divided in to two categories. 1)Value Types, 2) Reference type.

Value Type :

The data types which are capable of storing the data directly into their memory locations are known as "Value Types". Ex: int a=10;

Reference Type:

The data types which can't store the data directly into their memory location rather reffers to other memory location were data is stored, are known as "Reference Types". Ex: String s="LAKS".

Difference Between Value types and Reference Types

Value Types Reference Type
Store the data directly into their memory location Stores the directly into their memoray locations rather refers to other memory locations where data is stored
Memory is alloted at compile time Memory is alloted at run time
memory allocation is made with in the stack Memory allocation is made with the heap
CLR  not provide the "Automatic memory management" CLR does not provide the "Automatic memory management"

Boxing and Un Boxing

Boxing :

Boxing is the process of converting a variable from "value type to reference type".

Un Boxing :

un boxing is the process of converting a variable from "reference type to value type".

C ++ Introduction | Fundamentals of C++

LAKS Tutorials

Introduction of C++

C++ Programming language was developed by Bjarne Stroustrup and his team Bell Laboratories (AT &T USA) to help implement simulation projects in an object-oriented and efficient way. C ++ language was derived from C language. Here ++ is the increment operator in C.
In the year  1998 the ISO(International Organization for Standardization) approved standard for C++.

Characteristics of C++

C++ is not a purely object-oriented language but a hybrid that contains the functionality of the c programming language. Means that all the features of c language is available in C++.

  • Universally usable modular programs
  • Efficient, close to the machine programming
  • Portable programs for various platform
  • The main feature of C++ is supporting OOP (Object-Oriented-Programming)Concepts.
  • Basic concepts of Object-Oriented Programming

    It is necessary to understand some of the concepts used extensively in object-oriented programming.
  • Objects
  • Class
  • Data abstraction and encapsulation
  • Inheritance
  • Polymorphism
  • Dynamic Binding
  • Message passing

  • Advantages of OOP

    Object-Oriented programming offers several major advantages to software development.
  • Easy Re use Objects maintain themselves and can therefore be used as building blocks for other programs
  • Low maintenance requirement an object type can modify its own internal data representation without requiring changes to the application.
  • Reduced susceptibility to errors: an object control access to its own data. More specifically an object can reject erroneous access attempts.

    Applications of C

    LAKS Tutorials

    C language is more efficient and powerful we know that because of every where we can use c language or its features. We learn Application of C language.
    C programming is best known programming language. C programming is near to machine as well as human language so it is called as middle level programming language. C program also used to different  tasks such as networking related, OS related.

    Applications of C Programming

    1. C language is used for creating Computer Applications.
    2. Used in writing Embedded software.
    3. It is also used in developing verification software,test code for various applications and hardware products.
    4. C is used to implement different Operating System Operations.
    5. UNIX Kernel is completely developed in C Language.
    6. Firmware for various electronics,industrial and communications products which use micro controllers.
    7. For creating Compilers of different Languages which can take input from other language and applications convert into lower level machine dependent language.

    List of Applications of C Programming

    Operating Systems Language Compilers Modern Programs
    Simulators Network Drives Assemblers
    Utilities Print Spoolers Text Editors
    Language interpreters Embedded Systems Language compilers

    Components of Dot Net framework | CLS |Common Language Specification

    LAKS Tutorials

    Components of Dot net frame work. Laks Tutorial explains the components
    of Dot net frame work.
    1. CLR(Common Language Run Time)
      1. CLS (Common Language Specification)
      2. CTS (Common Type System)
      3. JIT (Just In Time Compiler)
      4. GC (Garbage Collector)
    2. Base Class Library 

    Common Language Specification

    Common Language Specification responsible to provide "Language Interoprability"

    Language Interaparability

    Providing code execution support that has been written in any other programming language is known as "Language Interoprability (LI)" Means write any program in some other languages like c,java, after writing the code will provide the execution of the code, which platform is supported for this execution that platform is known as "Language Interoporability".Language Interoparabilty is achieved by Managed Code and UnManaged Code.

    Managed Code

    The Code for which MSIL form is available after the language compiler compilation is executed directly by the CLR and is called as "Manged Code".The code execution process is called as "Manged Code Execution".
    In Manged code execution CLR will provide all the  features of .Net like Language Inseparability, Common Type System, JIT compilation.

    Un Manged Code

    Code that is developed early to dot net,for which there is no MSIL form is available is not executed directly by the CLR . Rather CLR will redirect the code to OS(Operating System ) for execution.This is called as "unmanaged code", and the code execution process is called as "un managed code execution". In UN Manged code execution CLR not provide any features of dot net like JIT compiler,CTS.

    CLS(Common Language Specification)

    Language Specification:

    Syntactical rules that we follow to write the programs in any programming language is known as Language specification. In Manged code execution process . Net supports 61 Programming languages every programming language has its own Language specification.
    Every programming language has its own language specification, one programming language can't understand the other programming language specification or syntactical rules but all these programming languages code executed by the CLR.
    CLR does not know or Can't understand any of the programming language language specification rather CLR acts its own language specification for MSIL.
    Any programming language compiler follow CLR's language specification and should generate MSIL accordingly.
    This language specification of CLR is common to all the supported dot net (61) programming languages. All Language Specification process is known as Common Language specification" in Dot net.
