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.

∙ 10y agoA wrapper class is a class that encapsulates the functionality of another class, component or primitive data type and that provides an alternate interface (often a simplified interface, known as a facade) to the underlying embedded member.

∙ 10y agoInterfaces are the declarations of functions and classes. Typically, interfaces are placed in header files thus allowing several sources to make use of the same interfaces.
The implementation of those interfaces is provided by the function or class definitions. All definitions are themselves declarations, thus functions and classes may also be defined at the point of declaration. However, it is good practice to keep implementations separate from interfaces, since consumers are only ever interested in the interface, never the implementation.

Is sql used in c plus plus and cobol language?
Not as part of the formal language, but you can use SQL in various languages, including C++ or Cobol, if you have an appropriate precompiler that allows you to interface with the desired DBMS, be it Oracle, DB2, or whatever. You can also use an interface, such as OCI, if you want. Again, none of these methods are strictly a part of the language.
Why need to declare header files compulsory in c plus plus but not in c?
The need to declare header files is not compulsory in C++. You may place all your code in a single source file if you so desire. However, header files are useful in that they separate interface from implementation and aid in hiding information.
How do you program an adc of pic in c plus plus?
Consult the device programmer's manual. Typically you will need an Application Programming Interface (API) suitable for the device in question. The appropriate API should be freely available from the device manufacturer.
What is the header file for using graphics in c plus plus?
There is no graphic.h in the standard C++ language. It typically ships with 3rd party C++ implementations that incorporate the Borland Graphic Interface or one of its variants, such as Embarcadero Builder. It can also be used with Dev C++ if you install the WinBGIM library. Its primary purpose is to provide Windows graphics support since C++ has no built-in graphics support of any kind.
Which languages support multiple interface?
If by interface you mean, a mechanism to achieve abstraction and create a blueprint for future implementation. Java/C#/C++ all allow for multiple interfaces(abstract classes in C++) to be implemented.
In C plus plus Interface is also known as?
I guess you mean Java, there is no interface in C++.
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.
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.
How do you make a GUI interface In C Language without using gtk plus?
Use Xlib. Or Qt. Or WinApi.

What is c plus c plus 2c plus c plus c equal?
c + c + 2c + c + c = 6c
B plus b plus b plus c plus c plus c plus c equals?
b + b + b + c + c + c + c = 3b + 4c
Symplify c plus c plus c plus c?

What is object oriented language in c plus plus?
C++ enables object oriented programming through the use of classes, where an object is an instance of a class. A class is essentially a data type, one that can store information (much like an int stores a value) and that provides an interface to that information.
What is c plus c plus c plus c plus c?
c + c + c + c + c = 5 * c.
