Inheritance is one of the most important concepts in object-oriented programming, together with encapsulation and polymorphism. Inheritance allows developers to create new classes that reuse, extend, and modify the behavior defined in other classes. This enables code reuse and speeds up development. With inheritance, developers can write and debug one class only once, and then reuse that same code as the basis for the new classes.

The class whose members are inherited is called the base class, and the class that inherits those members is called the derived class.

By default, all classes in. NET are inheritable. We can look at the class as a template of the object: it describes all the properties, methods, states and behaviors that the implementing object will have.

As mentioned, an object is an instance of a class, and a class does not become an object until it is instantiated. There can be more instances of objects based on the one class, each with different properties. Managed code is a code created by the. NET compiler. It does not depend on the architecture of the target machine because it is executed by the CLR Common Language Runtime , and not by the operating system itself.

CLR and managed code offers developers few benefits, like garbage collection, type checking and exceptions handling. On the other hand, unmanaged code is directly compiled to native machine code and depends on the architecture of the target machine. It is executed directly by the operating system. In the unmanaged code, the developer has to make sure he is dealing with memory usage and allocation especially because of memory leaks , type safety and exceptions manually.

Explain the difference between the while and for loop. Provide a. NET syntax for both loops. Both loops are used when a unit of code needs to execute repeatedly. The difference is that the for loop is used when you know how many times you need to iterate through the code. On the other hand, the while loop is used when you need to repeat something until a given statement is true. Boxing is the process of converting a value type to the type object, and unboxing is extracting the value type from the object.

While the boxing is implicit, unboxing is explicit. LINQ is a set of features that extends query capabilities to the. NET language syntax by adding sets of new standard query operators that allow data manipulation, regardless of the data source.

Supported data sources are:. In short, LINQ bridges the gap between the world of objects and the world of data. Discuss what garbage collection is and how it works. Provide a code example of how you can enforce garbage collection in.

Garbage collection is a low-priority process that serves as an automatic memory manager which manages the allocation and release of memory for the applications.

Each time a new object is created, the common language runtime allocates memory for that object from the managed Heap. As long as free memory space is available in the managed Heap, the runtime continues to allocate space for new objects.

However, memory is not infinite, and once an application fills the Heap memory space, garbage collection comes into play to free some memory. When the garbage collector performs a collection, it checks for objects in the managed Heap that are no longer being used by the application and performs the necessary operations to reclaim the memory.

Garbage collection will stop all running threads, it will find all objects in the Heap that are not being accessed by the main program and delete them. It will then reorganize all the objects left in the Heap to make space and adjust all the Pointers to these objects in both the Stack and the Heap.

To enforce garbage collection in your code manually, you can run the following command written in C :. NET application. It is a compiled code library used for deployment, versioning, and security. CLI assemblies contain code in CIL, and as mentioned, during compilation of CLI programming languages, the source code is translated into CIL code rather than into platform or processor specific object code. The short answer would be: in the Stack are stored value types types inherited from System.

ValueType , and in the Heap are stored reference types types inherited from System. We can say the Stack is responsible for keeping track of what is actually executing and where each executing thread is each thread has its own Stack. The Heap, on the other hand, is responsible for keeping track of the data, or more precise objects.

An interface merely declares a contract or a behavior that implementing classes should have. It may declare only properties, methods, and events with no access modifiers.

All the declared members must be implemented. It can declare fields too. In LINQ, deferred execution simply means that the query is not executed at the time it is specified.

Specifically, this is accomplished by assigning the query to a variable. When this is done, the query definition is stored in the variable but the query is not executed until the query variable is iterated over. For example:. You can also force immediate execution of a query. A delegate in. Using a delegate allows the programmer to encapsulate a reference to a method inside a delegate object.

The delegate object can then be passed to code which can call the referenced method, without having to know at compile time which method will be invoked. In addition, we could use delegate to create custom event within a class.

For example,. When break is used inside two nested for loops, control comes out of which loop, the inner or the outer for loop? You would know that System. Object is the parent class of all. NET classes; In other words all types in. NET whether implicit, explicit, or user-created derive from the System.

Object class. Most of these methods provide the basic implementation required of any type that a developer will work with in the. NET stack. While constants and read-only variable share many similarities, there are some important differences:.

Сьюзан равнодушно смотрела на ТРАНСТЕКСТ. Она понимала, что огненный шар, заточенный в керамическую клетку, скоро вырвется наружу и поглотит. Она почти физически ощущала, как этот шар поднимается вверх все быстрее, пожирая кислород, высвобождаемый горящими чипами.

Получалось, что АНБ фактически получило возможность вскрывать всю почту и затем пересылать ее без какого-либо уведомления. Это было все равно что установить жучки во все телефонные аппараты на земле. Стратмор попытался убедить Танкадо, что ТРАНСТЕКСТ - это орудие охраны правопорядка, но безуспешно: Танкадо продолжал настаивать на том, что это грубейшее нарушение гражданских прав. Он немедленно уволился и сразу же нарушил Кодекс секретности АНБ, попытавшись вступить в контакт с Фондом электронных границ.
