C++ examples for Class:Constructor
You can use a constructor initialization list to set the member variable:
#include <iostream> class Pool { private: double length {1.0}; double width {1.0}; double height {1.0}; public: // Constructors Pool(double lengthValue, double widthValue, double heightValue); Pool(); // No-arg constructor double volume(); // Function to calculate the volume of a pool }; // Constructor definition using an initializer list Pool::Pool(double lv, double wv, double hv) : length {lv}, width {wv}, height {hv} { std::cout << "Pool constructor called." << std::endl; }
It is the same as:
// Constructor definition Pool::Pool(double lengthValue, double widthValue, double heightValue) { std::cout << "Pool constructor called." << std::endl; length = lengthValue; width = widthValue; height = heightValue; }
