Description:
Create a class called "Set" in C++ using object-oriented techniques. The maximum number of elements in a Set is 100. Create the array to store the elements of the Set by using the "new" operator. The only type of elements that can be stored in a Set is an integer. Programmers may define objects of Set class in the ways shown in the following examples: int a[11]={10,0,1,2,3,4,5,6,7,8,9}; int b[6]={5,1,3,5,7,9}; int c[6]={5,0,2,4,6,8}; int d[3]={2,0,1}; int e[1]={0}; Set Nnatural ; //creates an empty set Set one_digit=a; //creates a set using an array s.t. the first element //of the array shows the size of the array Set odd=b; Set even=c; Set zero=0; //creates a set with single element 0 (i.e. {0}) Set zero_one=d; Set x=one_digit; //creates a set by usin an existing set //makes an exact copy of the existing set Set empty_set2=e; 1. Write necessary constructors (and a destructor) for above operations. 2. Write following functions: Insert: inserts an element into a set eg: odd.Insert(6) modifies odd as {1,3,5,6,7,9} Remove: removes an element from a set eg: odd.Remove(5) modifies odd as {1,3,7,9} Is_empty: tests whether the set is empty or not eg: odd.Is_empty() returns 0 Card: Finds the cardinality of a set eg: zero_one.Card() returns 2 3. Overload following operators: = : Assignment operation (between 2 sets) eg: odd=even; results in odd={0,2,4,6,8} + : Union of two sets eg: odd + even results in a set {0,1,2,3,4,5,6,7,8,9} * : Intersection of two sets eg: odd * even results in an empty set - : Difference of two sets eg: one_digit - even results in a set {1,3,5,7,9} == : Equality of two sets, if all members are same return 1, else 0 eg: one_digit == even returns 0 one_digit == x returns 1 [] : Membership of an element to a set eg: odd[3] returns 1 odd[2] returns 0 < : Subset operator eg: odd < one_digit returns 1 > : Superset operator eg: one_digit > one returns 1 << : Output a set. Elements will be separated by a blank and an end of line at the end. >> : Input a set. Read the number of elements that will be input first. Then, read the elements, which are separated by a blank.

Deliverables:
this is the rest of the specifications: Create a class called "Bag" in C++ using object-oriented techniques. The Bag class will be a subclass of the class Set. In a Bag the same element can be repeated any number of times. Accordingly some existing Set functions should be redefined in a Bag class. Also some new functions will be defined. The maximum number of elements in a Bag is 1000. Create the array to store the elements of the Bag by using the "new" operator. The only type of elements that can be stored in a Bag is an integer. Bag objects can be constructed in different ways: int a[4]={1,2,3,4}; int b[10]={0,0,0,1,1,2,3,8,9,9}; int c[]={0,1,1,8,9}; int d[]={0,0,8}; Bag empty_bag; //creates an empty bag Bag bag1(b,10); //creates a bag by initializing it with an array //second parameter shows the size of the array Bag bag2=bag1; //creates a bag from an existing bag Bag bag3=set1; //creates a bag from an existing set Bag bag4(c,5); Bag bag5(d,3); 1. Write necessary constructors to handle the above declarations. 2. The following functions/operator will be inherited from the Set class: Insert: inserts an element into a bag unlike a set, an existing element can also be instered Remove: removes an element from a bag since each element can have several copies remove may remove only one copy Is_empty: tests whether the bag is empty or not Card: Finds the cardinality of a bag each occurence of an element contributes to the cardinality = : Assignment operation (between 2 bags) Also overlaod another version; assign a set into a bag + : Union of two bags Allows repetitions. * : Intersection of two bags Allows repetitions. - : Difference of two bags eg: bag4 - bag5 results in a bag {1,1,9} == : Equality of two bags, if all members are same return 1, else 0 [] : Count of an element in a bag eg: bag5[0] returns 2; bag5[1] returns 0 < : Subbag operator eg: bag5 < bag1 returns 1 > : Superbag operator eg: bag4 > bag5 returns 0 << : Output a bag. Each element will be printed with its count as follows: eg: cout<<bag5; will print 0:2 8:1 >> : Input a bag. Read the size of the bag first, and then read that many integers separated by a blank (or any delimeter). 3. Add the following functions. sum : find the sum of the integers in a bag, and return it product : find the product of the integers in a bag, and return it 4. Define the following function: void test(Set & ps1, Set & ps2) { Bag tb(ps1); int i; cout<>ps2; tb=ps2; cout<<tb; cin>>i; cout<<tb[i]; } Test this function (by calling it from your main function) with different type paramaters (like 2 sets, 2 bags, a bag and a set, etc.) and make sure it works correctly allways. If necessary convert some of the functions inherited from class Set to virtual. Note that we can change this test funtion also (prototype of the function will not be changed), so you should better try other functions.

Hi! I'm sure that I can help you with your project. I'm a professional programmer working in C++ for about 4 years and I'm sure that I won't let you down. I can provide you the source code in a very short time and the bid is negociable. If you have questions , sugestions or other misunderstanding feel free to ask.

Thanks.
