Answers7). what is "Common Language Runtime" (CLR)?
- hr@percosoft.com February 10, 2022 in India
CLR is .NET equivalent of Java Virtual Machine (JVM). It is the runtime that converts a MSIL code into the host machine language code, which is then executed appropriately. The CLR is the execution engine for .NET Framework applications. It provides a number of services, including:
- Code management (loading and execution).
- Application memory isolation.
- Verification of type safety.
- Conversion of IL to native code.
- Access to metadata (enhanced type information).
- Managing memory for managed objects.
- Enforcement of code access security.
- Exception handling, including cross-language exceptions.
- Inter operation between managed code, COM objects, and per-existing DLL's (unmanaged code and data)
- Automation of object layout.
- Support for developer services (profiling, debugging, and so on).| Report Duplicate | Flag | PURGE

- hr@percosoft.com February 10, 2022 in India
CTS define all of the basic types that can be used in the .NET Framework and the operations performed on those type. All this time we have been talking about language interoperability, and .NET Class Framework. None of this is possible without all the language sharing the same data types. What this means is that an int should mean the same in VB, VC++, C# and all other .NET compliant languages.

Answers4). what is the difference between "using System. Data;" and directly adding the reference from "Add References Dialog Box"?
- hr@percosoft.com February 10, 2022 in India
When u compiles a program using command line, u add the references using /r switch. When you compile a program using Visual Studio, it adds those references to our assembly, which are added using "Add Reference" dialog box. While "using" statement facilitates us to use classes without using their fully qualified names.
For example: if u have added a reference to "System.Data.SqlClient" using "Add Reference" dialog box then u can use SqlConnection class like this:
System.Data.SqlClient.SqlConnection
But if u add a "using System.Data.SqlClient" statement at the start of our code then u can directly use SqlConnection class. On the other hand if u add a reference using "using System.Data.SqlClient" statement, but don't add it using "Add Reference" dialog box, Visual Studio will give error message while we compile the program.| Report Duplicate | Flag | PURGE

Answersdifferences between object-oriented programming and structural programming?
- hr@izetam.com February 10, 2022 in United States
Object-oriented Programming
Follows a bottom-up approach.It provides data hiding.
It is used to solve complex problems.
It allows reusability of code that reduces redundancy of code.
It is based on objects rather than functions and procedures .
It provides more security as it has a data hiding feature.
It focuses on data .
More abstraction more flexibility.
Structural Programming
Follows a top-down approach.
. Data hiding is not allowed.
It is used to solve moderate problems.
Reusability of code is not allowed.
. It provides a logical structure to a program in which the program is divided into functions.
It provides less security as it does not support the data hiding feature.
More abstraction more flexibility.
