The only difference between a struct and a class in C++ is that struct members are public by default while class members are private by default. Other than that they act and behave in exactly the same way and are both used to define classes. By convention, struct is used exactly as it would be used in C, with all public members and no member functions, to provide backward compatibility with C-style code.

What are similarities and differences between computer case and system unit?
System unit refers to the housing plus the components inside the box. While a computer case is just a 'case' itself w/o the hardware components attached to it.

How much did a ticket on the titanic cost for second class for the British?
Second class costed 12 pounds (1200 dollars today). First Class: 870 pounds w/ parlor suite ($83.200 today). --> plus 30 pounds w/ berth ($2975 today). Second Class: 12 punds ($1200 today). Third Class: 3 pounds ($298 to $793 today). Notice that with only 1 single first class ticket the ship was able to pay all the staff for between 4 to 8 months since they only earned 2 pounds (skilled ones) and 1 pound or less (the less or non skiled ones).

Sample code of typedefstruct in c plus plus?
You don't need a typedef to declare a struct in C++. A struct is declared exactly the same way that you would declare a class, the only difference being that struct members are public by default, while class members are private by default. Aside from that the class and struct keywords are completely interchangeable.
What is a class in c plus plus how does it compare with structure in c?
A struct in C is a POD (plain old data) type. A class in C++ can also be a POD for backward compatibility with C code, but more typically combines data with methods that operate upon the data, including constructors and initialisers. Classes in C++ can be declared using either the struct or class keyword. By convention you will typically use struct to define POD data types and class to define more complex data types. The only practical difference between a struct and a class is that classes use private access and inheritance by default while struct uses public access and inheritance by default. Thus the following two class definitions are functionally the same: struct A { A():m_data(0) {} // public access by default private: int m_data; }; class B { int m_data; // private access by default public: B():m_data(0) {} };
Demonstrate single inheritance in C plus plus?
struct base1 { // ... }; struct base2 { // ... }; struct derived1 : public base1 // single inheritance { // ... }; struct derived2 : public base1, public base2 // multiple inheritance { // ... };
How do you differentiate between classes and structures with appropriate examples in c plus plus?
The only difference between a class and struct in C++ is that a struct's members are public by default while a class' members are private by default. For example: #include<iostream> struct foo{int m_data;}; class bar{int m_data;}; int main() { foo f; bar b; f.m_data=100; // ok; m_data is public by default. b.m_data=200; // access denied; m_data is private by default. return(0); } To make bar work the same as foo, you must declare m_data as a public member: class bar{ public: int m_data; }; To make foo work the same as the original bar, you must declare m_data as a private member: struct foo{ private: int m_data; }; Aside from that, structs and classes are treated as being the same thing: they are both used to define a type of object. In other words, they both define a class of object. Note that the struct keyword is inherited from C, but a C-style struct is simply an user-defined type that can have one or more member attributes (data fields), but that has no member methods associated with it. Despite that, a C-style struct is still a good C++ struct, because the C-style struct members are always public and cannot be declared private (only C++ struct members can be declared private).
Programme to implement single and multilevel inheritance taking employee as sample base class in c plus plus?
struct employee { }; struct supervisor : employee { // single inheritance -- a supervisor inherits all the public and protected properties of an employee. }; struct manager : supervisor { // multilevel inheritance -- a manager inherits all the public and protected properties of a supervisor (and therefore an employee). };
What is the difference between destructors in c plus plus and c sharp?
In C# only class instances can have a destructor, whereas both class and struct instances can have a destructor in C++. While syntactically similar, a C++ destructor executes exactly as written, whereas a C# destructor merely provides the body of the try clause of the class' finalize method.
What is the difference between a structure in C and a structure in C-plus-plus?
Not much. C++ structures are the same, i.e., still declared with "struct".. Are you sure that you didn't mean to ask: "What's the difference between a structure and a class?" Cause, that's the main (DRUMROLL PLEASE) power of C++, among other things. I think there is a difference in them. In struct of C there are no Member functions allowed .( you can use function pointer but not the definition in the structure ). But in C++ you have that flexibility . A C++ struct is exactly the same as a C++ class, except that struct members are public by default while class members are private by default. Access to individual members can be overridden in the declaration thus either can be used for the same purpose. C++ programmers use classes to define most object types and reserve the struct type for backward-compatibility with C.A C struct has member variables but has no methods. Accessibility cannot be defined, thus all members are effectively public at all times.

Is inheritance polymorphism possible in structure in c plus plus?
Yes. A C++ struct is exactly the same as a C++ class. The only difference is that struct members are public by default, whereas class members are private by default. Other than that, they work exactly the same way. Typically, you will use a struct when there is no need to encapsulate the data members (public access only), or when you need backward compatibility with C-style code. A C-style struct has only public data members (none of which can be a class of course, but may be another struct), but it has no methods whatsoever. Thus you need to disable the compiler-generated default and copy constructors, the destructor and the assignment operator. This is achieved by declaring them without a function body (no curly braces).
What is the name of the structure type in C plus plus?
The same as in C, struct.
What are the differences between a struct data type and a class data type in c plus plus?
A struct declares all members public by default, whereas a class declares all members private by default. That is really the only difference. Structs are from C and classes from C++, you can use both structs and classes in C++ but only structs in C.
