A C struct only has public member variables whereas a C++ class combines member variables with member functions; the methods that operate upon the data. Moreover, each member of a class can be assigned a different level of access from public, protected or private access, thus limiting the member's exposure. This allows classes to hide data and implementation details from outside of the class, exposing only as much as is necessary in order to use the class. Thus the class becomes entirely responsible for the integrity of its data, while its methods act as the gatekeepers to that data.


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.

What are the advantages of structure in c plus plus?

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.


Definition of structure in c plus plus?

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).


Basic structure of c n c plus plus?

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.


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.

That depends on the use. Each has advantages in different applications. Without more specifics on your application I cannot comment usefully.

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 are the Advantages of c over c plus plus?

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.

The fields in a c program are by default private is true or not?

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.

What is the difference between structure and class with example?

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. };
