Constructors declared explicit will notbe considered for implicit conversions. For example:class X {public:explicit X(int); //legalexplicit X(double) { //legal // ... }};explicit X::X(int) {} //illegalAn explicit constructor cannot take part in implicit conversions. It canonly be used to explicitly construct an object. For example, with the classdeclared above:void f(X) {}void g(int I){f(i); // will cause error}void h(){X x1(1); // legal}The function call f(i) fails because there is no available implicitconversion from int to X.Note It is meaningless to apply explicit to constructors with multiplearguments, since such constructors cannot take part in implicit conversions.END C++ SpecificprotectedC++ Specific —protected: [member-list]protected base-classWhen preceding a list of class members, the protected keyword specifiesthat those members are accessible only from member functions and friends ofthe class and its derived classes. This applies to all members declared upto the next access specifier or the end of the class.When preceding the name of a base class, the protected keyword specifiesthat the public and protected members of the base class are protectedmembers of the derived class.Default access of members in a class is private. Default access of membersin a structure or union is public.Default access of a base class is private for classes and public forstructures. Unions cannot have base classes.For related information, see public, private, friend, and Table of MemberAccess Privileges.END C++ SpecificExample// Example of the protected keywordclass BaseClass {protected: int protectFunc();};class DerivedClass : public BaseClass{ public:int useProtect() { protectFunc(); } // protectFunc accessible fromderived class};void main(){BaseClass aBase;DerivedClass aDerived;aBase.protectFunc(); // Error: protectFunc not accessibleaDerived.protectFunc(); // Error: protectFunc not accessible in derivedclass } How do you code an infinite loop in C?
