Read MoreDifference between private, public, and protected modifiers in C++
Data hiding is one of the important features of Object Oriented Programming which allows preventing the functions of a program to access directly the internal representation of a class type. The access restriction to the class members is specified by the labeled access modifiers − public, private, and protected sections within the class body.The default access for members and classes is private.Exampleclass Base { public: // public members go here protected: // protected members go here private: // private members go here };A public member is accessible from anywhere outside the class but within a program. ...
Read MoreWhat does the explicit keyword mean in C++?
The explicit keyword in C++ is used to mark constructors to not implicitly convert types. For example, if you have a class Foo −class Foo { public: Foo(int n); // allocates n bytes to the Foo object Foo(const char *p); // initialize object with char *p };Now if you tryFoo mystring = 'x';The char 'x' is implicitly converted to int and then will call the Foo(int) constructor. But this is not what was intended. So to prevent such conditions and make the code less error-prone, define the constructor as explicit −Example class Foo { public: ...
