What is the Difference between b and c class MS pipe?
The main difference is the thickness of the pipe Compare to A Class pipe B Class pipe thickness is more.Like that Compare to B class pipe C Class pipe thickness is more.
What is the Need for structure in c plus plus?
There is no pressing need for structures in C++. Anything you can do with a structure you can also do with a class. The only real difference is that structure members are public by default, whereas class members are private by default, but they both work exactly the same way otherwise. The struct keyword is retained for backward compatibility with C, but a C++ struct is not the same as a C struct unless it is has no interface and all the member variables are implicitly public. Most C++ programmers will use structures to differentiate simple data structures (values) from fully-encapsulated classes (objects). The complexity of the data and its interface is usually the deciding factor in whether to use a class or a structure. For trivial classes the time and effort that goes into developing the interface is often unnecessary so a structure will often suffice. But if the class is to be distributed to third parties then it's better to provide a more robust interface, even for trivial classes, and to avoid C-style structures entirely.
Interface in C plus plus?
Unless by "interface" you mean a user interface...C++ does not have interfaces per se, at least not in the same sense as, say, Java. In a C++ class, a function declared pure virtual makes the class non-instantiable and forces derived classes that want to be instantiable to provide an implementation. This has exactly the same effect as the interface concept of Java. So in C++, interface is just a synonym for abstract base class.
How can access an interface from another interface and how to access from a class?
Interfaces are designed to do exactly that: to interface or to interact. In object-oriented programming languages such as C++, you can incorporate up to three different interfaces per class. The private interface is accessible only to the class itself and to friends of the class. The protected interface is the same as the private interface but is also accessible to derivatives of the class. The public interface is accessible to any code. For one interface to interact with another interface, the first must have access to the second. If the first is a friend of the second or both are members of the same class, the first has unrestricted access to the private, protected and public interfaces of the second. If the first is derived from the second but is not a friend, the first only has access to the protected and public interfaces of the second. If the first is completely separate from the second, the first only has access to the public interfaces of the second.
What are the differences between an abstract class and an interface in java?
They are very different. An abstract class is a class that represents an abstract concept (google define "abstract" if you're unsure) such as 'Thoughts' or 'BankAccount'. When a class is defined as abstract it cannot be used (directly) to create an object. Abstract classes are used as super-classes so that all of their subclasses inherit all methods. Interfaces can be thought of as contracts with all of their implementing classes. They simply require all implementing classes to have methods with the same signature as that defined in the interface, but such methods can behave as appropriate. Hope that helps :)
What is the difference between class inheritance and interface inheritance?
interface inheritance is a misleading term. Interface inheritance would be equivalent to the union of the method signatures of interfaces ( no typo here, an interface may implment multiple other interfaces) Class inheritance - single hierarchy (in C#), and not only the methods are inherited, but also the data members. (interface in C# cannot define data members)
When you define a c plus plus class what items are considered part of the interface?
The interface of a C++ class is the public methods and attributes that are exposed by the class. In a pure abstract base class, the interface is enforced by the compiler in each of the derived child classes.
What is the difference between the Linux shell and C?
C is a programming language. A shell is an interface.

Can you use multiple inheritance in .NET?
Multiple inheritance in C# In C#, the classes are only allowed to inherit from a single parent class, which is called single inheritance. But you can use interfaces or a combination of one class and interface(s), where interface(s) should be followed by class name in the signature.
Why you use public mode in c plus plus?
To expose an interface to the class members. Without an interface of some kind, an object would be useless.
What are the differences between a C structure and C class?
The main difference between a class and a structure is that structures are always public whereas classes are private by default. Classes give greater control as the interface can be engineered such that only code that requires access to specific class members gains that access. Everything else can be hidden within the class itself. Note that C does not support classes, period. Classes are only supported by C++. However C++ also supports C structures for backward compatibility with C-style code.
What is the difference between Google Class A and Class C shares?
The main difference between Google Class A and Class C shares is in their voting rights. Class A shares come with voting rights, allowing shareholders to have a say in company decisions, while Class C shares do not have voting rights.
What is the difference between a class A felony and a class C?
Class A is the most serious and has more severe penalties.

What is the difference in a class a subnet mask and a class c?
The octets are different - a class a is 255.0.0.0 and a class C is 255.255.255.0 for a default subnet mask. Of course, if you are subnetting then this doesn't apply.
