Description
Develop a class called Weight that is an abstract data type (ADT) for an weight. The complete class will include all the following member functions: A constructor to set pound and ounce; ex. 2lb 12oz can be set as Weight item1(2,12); If users set the ounce part grater than 15, like Weight item1(2,20), it should be converted to 3lb 4oz. A constructor to set ounce; ex. 36oz can be set as Weight item2(36); It should be converted to 2lb 4oz. A default constructor (takes no input) that sets 0lb 0oz. Public member function, “get_Pounds()” that returns the pound part of weight. Public member function, “get_Ounces()” that returns the ounce part of weight. The return value must be between 0 to 15. Note 16oz=1lb. Public member function, “get_Grams()” that returns the weight in grams. use 1oz=28.35g A friend function, “Weight add(const Weight& w1, const Weight& w1)”, which adds two Weight objects and returns a new object of Weight that stores the result. A friend function, “comp compare(const Weight& w1, const Weight& w1)”, which compares two Weight objects and returns comp type (enum type) variable of: GREATER if w1>w2, LESS if w1<w2, or EQUAL if w1=w2. comp type is enum type defined by “enum comp{GREATER=1, LESS=1,EQAUL=0};” see Link (http://en.cppreference.com/w/cpp/language/enum) you may define private member functions. (helper functions) Add “const” modifier for member function that does not modify member variables. Member variables must be private. It is your decision how to store the information, pounds and ounces. Add class definition and implementation into the code below. What is ‘switch’? See Link (http://en.cppreference.com/w/cpp/language/switch) #include // enumerate “comp” type for “compare” function enum comp{GREATER=1, LESS=-1,EQUAL=0}; const double ounce2grams = 28.35; 4/23/2018 Homework 06 https://tulane.instructure.com/courses/2165899/assignments/13465091 2/2 ///////////////////////////////////// // ADD YOUR CODE HERE // ///////////////////////////////////// // main function int main(int argc, const char * argv[]) { Weight item1(2,12); Weight item2(36); std::cout << “Item1 is ” << item1.get_Pounds() << “(lb) ” << item1.get_Ounces() << “(oz).\n”; std::cout << “Item2 is ” << item2.get_Pounds() << “(lb) ” << item2.get_Ounces() << “(oz).\n”; std::cout << “Item1 is “; switch(compare(item1,item2)) { case GREATER: std::cout << “greater than “; break; case LESS: std::cout << “less than “; break; case EQUAL: std::cout << “equal to “; break; default: std::cout << “Something Wrong “; } std::cout << “Item2\n”; Weight total = add(item1,item2); std::cout << “The total weight is ” << total.get_Pounds() << “(lb) ” << total.get_Ounces() << “(oz), which is equivalent to” << total.get_Grams() << “(g)\n”; return 0; } Output will be: Item1 is 2(lb) 12(oz). Item2 is 2(lb) 4(oz). Item1 is greater than Item2 The total weight is 5(lb) 0(oz), which is equivalent to 2268(g)
