Class & Objects

Class & Objects The mechanism that allows you to combine data and the function in a single unit is called a class. Once a class is defined, you can declare variables of that type. A class variable is called object or instance. In other words, a class would be the data type, and an object would be the variable. Classes are generally declared using the keyword class, with the following format: class class_name {   private:      members1;   protected:      members2;   public:      members3;}; Where...
