Question

 (In hurry) Import file (day.txt) Note: customer1,item1;customer2,item2;customer3,item3; 

 1. Create a class called "Purchase", this class will have two member variables: 

     a. Customer 

     b. Item 

 2. Create an array of type purchase. There is a combined total of 15 purchases. 

 3. Parse all purchase data from all three files and store into your purchase array. 

 4. Sort the array in ascending order(do not use STL) 

            The array should be sorted by the following criterea: 

                 1. Customer Number - Customer 100 should come before customer 200, and both 

                    of those customers should come before customer 300. 

                 2. Item Number - If two or more purchases are made by the same customer, 

                    then you must sort according the item number. 

             For example, assume you have the following: 

                    100,1A;200,1B;100,1C;100,1B; 

                    When parsed and sorted, your array should look like the following: 

                    arr[0]: Customer: 100, Item: 1A 

                    arr[1]: Customer: 100, Item: 1B 

                    arr[2]: Customer: 100, Item: 1C 

                    arr[3]: Customer: 200, Item: 1B 

 5. Print out the array onto the console
