Note that in C++, a struct is exactly the same as a class, other than the fact that the members of a struct are public by default while members of a class are private by default, unless explicitly declared otherwise. Aside from that they operate in exactly the same way. In other words, a C++ struct is not the same as a C struct.
advantage of storage classes
They are primarily included to retain compatibility with C. However, structures are public by default. So if you don't require the data hiding capability of a class, a struct is a suitable alternative. Also, when mixing C and C++ code, there may be a requirement to typecast a class to a struct and vice versa.
A structure is a collection of variables referenced under one name, providing a convenient means of keeping related information together. A structure declaration forms a template that may be used to create structure objects (that is, instances of a structure). The variables that make up the structure are called members. (Structure members are also commonly referred to as elements or fields).
The basic structure of a C or C++ program is built around types. A structure is a type. A function is a type. A class is a type. All of these types can be built from primitive (built-in) types and can be used to create ever-more complex types.
Structures are the same as classes in C++. The only difference is that structure members are public by default while class members are private by default, but both define a class of object and both are initialised via a class constructor initialisation list. struct my_object { my_object(const int data): m_data(data) {} private: int m_data; }; The above struct is no different to the following class: class my_object { int m_data; public: my_object(const int data): m_data(data) {} };

class is defined in c++ my dear so in C there is no structure of class.for c++ class private { int x[10],y; cout
That depends on the use. Each has advantages in different applications. Without more specifics on your application I cannot comment usefully.

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.
There are no advantages of C over C++ as such. Everything you can do in C you can also do in C++. However, by taking advantage of C++ object oriented programming, generic programming and template meta programming as well as C-style coding, you can produce more efficient machine code far more easily and more quickly than with C alone.
Because piping class B was over populated, they needed a new piping class. For some reason they decided to skip C and go straight to piping class D
Class C.

I guess you mean C++, not C.Data fields of a structure/union are public by default,those of a class are private by default.

Structures are public by default whereas classes are private by default. Other than that they are exactly the same. struct s { int num; // s.num is accessible outside of the structure }; class c { int num; // c.num is only accessible to the class itself. };
