What Are The Difference Between Sequential And Indexed File System' title='What Are The Difference Between Sequential And Indexed File System' />C Interview Questions And Answers. What is C C is the best language for writing Microsoft. NET applications. C provides the rapid application development found in Visual Basic with the power of C. Its syntax is similar to C syntax and meets 1. Read a file line by line You are encouraged to solve this task according to the task description, using any language you may know. COBOL Tutorial studay material sequential indexed relative files, GOTO etc., Mainframe Cobol files. OpenSCAD is a 2D3D and solid modeling program which is based on a Functional programming language used to create models that are previewed on the screen, and. Returns information about all the waits encountered by threads that executed. You can use this aggregated view to diagnose performance issues with SQL Server and also. Im a big supporter of nonsignificant part numbers. This means that the number cant tell you anything about what you are looking at. You cant tell the difference. OOPs like the following Abstraction. Encapsulation. Polymorphism. Inheritance. To know more about C Language read the following article The latest version of C is C 6. What is an ObjectAccording to MSDN, a class or struct definition is like a blueprint that specifies what the type can do. An object is basically a block of memory that has been allocated and configured according to the blueprint. A program may create many objects of the same class. Objects are also called instances, and they can be stored in either a named variable or in an array or collection. Client code is the code that uses these variables to call the methods and access the public properties of the object. In an object oriented language such as C, a typical program consists of multiple objects interacting dynamically. Objects helps us to access the member of a class or struct either they can be fields, methods or properties, by using the dot. To know more about object read the following links 3. What is Managed or Unmanaged Code Managed CodeThe code, which is developed in. Sphinx is a fulltext search engine, publicly distributed under GPL version 2. Commercial licensing eg. NET framework is known as managed code. This code is directly executed by CLR with the help of managed code execution. Any language that is written in. NET Framework is managed code. Unmanaged Code. The code, which is developed outside. NET framework is known as unmanaged code. Applications that do not run under the control of the CLR are said to be unmanaged, and certain languages such as C can be used to write such applications, which, for example, access low level functions of the operating system. Background compatibility with the code of VB, ASP and COM are examples of unmanaged code. Unmanaged code can be unmanaged source code and unmanaged compile code. Unmanaged code is executed with the help of wrapper classes. Wrapper classes are of two types CCW COM Callable Wrapper. RCW Runtime Callable Wrapper. What is Boxing and Unboxing Answer Boxing and Unboxing both are used for type conversion but have some difference Boxing Boxing is the process of converting a value type data type to the object or to any interface data type which is implemented by this value type. When the CLR boxes a value means when CLR is converting a value type to Object Type, it wraps the value inside a System. Object and stores it on the heap area in application domain. Example Unboxing Unboxing is also a process which is used to extract the value type from the object or any implemented interface type. Boxing may be done implicitly, but unboxing have to be explicit by code. Example The concept of boxing and unboxing underlines the C unified view of the type system in which a value of any type can be treated as an object. For more details read this 5. What is the difference between a struct and a class in CAnswer Class and struct both are the user defined data type but have some major difference Struct. The struct is value type in C and it inherits from System. Value Type. Struct is usually used for smaller amounts of data. Struct cant be inherited to other type. A structure cant be abstract. No need to create object by new keyword. Do not have permission to create any default constructor. Class. The class is reference type in C and it inherits from the System. Object Type. Classes are usually used for large amounts of data. Classes can be inherited to other class. A class can be abstract type. We cant use an object of a class with using new keyword. We can create a default constructor. For more details just go with the following link 6. What is the difference between Interface and Abstract ClassAnswer Theoretically their are some differences between Abstract Class and Interface which are listed below A class can implement any number of interfaces but a subclass can at most use only one abstract class. An abstract class can have non abstract methods concrete methods while in case of interface all the methods has to be abstract. An abstract class can declare or use any variables while an interface is not allowed to do so. In an abstract class all data member or functions are private by default while in interface all are public, we cant change them manually. In an abstract class we need to use abstract keyword to declare abstract methods while in an interface we dont need to use that. An abstract class cant be used for multiple inheritance while interface can be used as multiple inheritance. An abstract class use constructor while in an interface we dont have any type of constructor. To know more about the difference between Abstract Class and Interface go to the following link 7. What is enum in C Answer An enum is a value type with a set of related named constants often referred to as an enumerator list. The enum keyword is used to declare an enumeration. It is a primitive data type, which is user defined. An enum type can be an integer float, int, byte, double etc. How To Use Atheros Eeprom Tool. But if you used beside int it has to be cast. An enum is used to create numeric constants in. NET framework. All the members of enum are of enum type. Their must be a numeric value for each enum type. Installing Slackware From Usb Unetbootin more. The default underlying type of the enumeration element is int. By default, the first enumerator has the value 0, and the value of each successive enumerator is increased by 1. Dow Sat, Sun, Mon, Tue, Wed, Thu, Fri  Some points about enum. Enums are enumerated data type in c. Enums are not for end user, they are meant for developers. Enums are strongly typed constant. They are strongly typed, i. Enumerations enums make your code much more readable and understandable. Enum values are fixed. Enum can be displayed as a string and processed as an integer. The default type is int, and the approved types are byte, sbyte, short, ushort, uint, long, and ulong. Every enum type automatically derives from System. Enum and thus we can use System. Enum methods on enums. Enums are value types and are created on the stack and not on the heap. For more details follow the link 8. What is the difference between continue and break statements in C Answer Using break statement, you can jump out of a loop whereas by using continue statement, you can jump over one iteration and then resume your loop execution. Eg. Break Statement using System  using System. Collections  using System. Linq  using System. Text    namespace breakexample                 Class brkstmt               public static void mainString args                   for int i  0 i lt  5 i                       if i  4                           break                                            Console.
