final keyword in c++ | C++ 11

final keyword (for virtual function and for class) :



Making class final make sure that the no class can derived from final class.
class CAT final {    // no class can be derived from CAT
   ...
};

    
Making virtual function final make sure that the no class can override final virtual function.

 class Dog {
   virtual void FUNC() final;  // No class can override FUNC() 
};

const used with functions

const used with functions : class Dog {    int age;    string name; public:    Dog() { age = 3; name = "dummy"; }         // const parameters and these are overloaded functions    void setAge(const int& a) { age = a; }    void setAge(int& a) { age = a; }         // Const return value    const string& getName() {return name;}         // const function and these are overloaded functions    void printDogName() const { cout << name << "const" << endl; }  // value of name can't be modified    void printDogName() { cout << getName() << " non-const" << endl; } }; int main() {    Dog d;    d.printDogName();        const Dog d2;    d2.printDogName();     }

Structured Bindings

Returning multiple Values from function C++ 11 vs C++ 17 Returning compound objects Iterating over a compound collection Direct initialization Returning multiple Values from function C++ 11 vs C++ 17 :  C++ 11 (std::tie): std::tuple mytuple() {     char a = 'a';     int i = 123;     bool b = true;     return std::make_tuple(a, i, b);  // packing variable into tuple } To access return value using C++ 11, we would need something like: char a; int i; bool b; std::tie(a, i, b) = mytuple();  // unpacking tuple into variables Where the variables have to be defined before use and the types known in advance. C++ 17 : auto [a, i, b] = mytuple(); Returning compound objects :  This is the easy way to assign the individual parts of a compound type (such as a struct, pair etc) to different variables all in one go – and have the correct types automatically assigned. So let’s have a look at an ...

POST 1 : std::thread in c++ | C++ 11

std::thread   C++  Thread support library std::thread. Threads enable programs to execute across several processor cores.
