C# is an object-oriented programming language developed by Microsoft that aims to combine the computing power of C++ with the ease of use of Visual Basic. It is based on C++ but also contains features similar to Java. C# can be used to develop both executable application programs and reusable component libraries. It includes features like versioning support, events, type safety, garbage collection, and unsafe memory manipulation capabilities.

- 2. What is a C#? C# (pronounced "C-sharp") is an object-oriented programming language from Microsoft. That aims to combine the computing power of C++ with the programming ease of Visual Basic. C# is based on C++ and contains features similar to those of Java.

- 6. C# COMPONENTS C# contains many different components, including: Versioning support, so that the base and derived classes- templates that define how an object performs and it remain compatible as we develop them. Events, so that the program can notify clients of a class about something that has happened to an object. Type safety and verification that increases reliability and ensures code security. Garbage collection, so that the program can identify objects that program can no longer reach. Unsafe mode, where it can use pointers to manipulate memory outside the garbage collector’s control, including methods and properties.

- 8. Difference between Windows & Console application in C# Windows application Console application The windows application has But the console application is the design time form not having any design time It is like VB due to the form presence of the design time It is like C or C++ due to the form absence of the design time The output will be displayed form in the Run time form as like The output will be displayed VB in the Command Prompt

- 10. CLASS: A class is a template that defines the form of an object. Fields: A fields (i.e) which are objects or values contained in a class or structure. Methods: A method is a code block containing a series of statements. In C#, every executed instruction is done so in the context of a method. Method parameters: The Method Parameters are nothing but they simply allow information to be passed into and out of a method.
- 11. Method Invocation: Method Invocation is nothing but calling the calling the method for another time. Local variable: A local variable is a type of variable that can be used where the scope and extent of the variable is within the method or statement block in which it is declared. Static method: Static methods have no instances. They are called with the type name. They are slightly faster than instance methods because of this, Static methods can be public or private.
- 12. APPLICATIONS OF C# This Visual C# was used for variety of application that are supported by the .Net plat forms, such as It is used for developing Console applications and Windows applications. It is used for developing Windows controls It is used for developing ASP.NET projects It is used for developing web controls It is used for providing web services It is used for developing .NET component library
- 13. Major Highlights of C# It is the Brand new language derived from C/C++ family. It is the First Compound Oriented Programming(COP) Language. It Simplifies & modernizes the C++. It is the only COP language available today. It is the only language designed for the .Net frame work.
