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) {}
};
It's a wrapper for a discretionary access control list (DACL) structure. It is not part of the C++ standard, it's a Microsoft-specific class. Consult the MSDN for more information.
The same as in C, struct.
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.
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.
Yes.
The basic control structure in C++ is the if statement.
No.
