The following is the business environment of Enterprise Car Rental. A car is manufactured by one manufacturer only. A manufacturer manufactured at least one of Enterprise's cars. Acar could have had many maintenance events (but a brand new car may not have had any, yet.) A car may not have been rented to any customers (again, the case of a brand new car) or to many customers. A customer may have rented many cars from Enterprise, and to be in Enterprise's business environment must have rented at least one. Please draw the ERD for the above business. Include any and all attributes you think are required such as Customer Details, etc. Convert the ERD to tables and convert the ERD into tables based on the rules discussed in class.
Note: If you are making any assumptions, do mention them explicitly.
Grading Criteria (partial marking will be therel:
10 points for all correct create tables
14 points for all correct relationships
8 points to all correct primary keys
8 points if it has all entities

Write a program that uses a widgetviewer object to do the following: generate two random integers between 1 and 9 (inclusive). name one of them x, the other y. display them to the user using jlabel objects. create a jlabel object displaying the text "enter an operation number." create a jtextfield for the user's input. create a jbutton displaying the text "press here when you've entered your operation." use addandwait to add it to the widgetviewer object. when the user clicks the jbutton, evaluate operation in the following order to determine the one and only mathematical operation to perform on x and y. use a jlabel to display the result. if operation is between 1 and 10 inclusive, add x and y. if operation is evenly divisible by 4, subtract y from x. if operation is evenly divisible by 5, use integer division to divide y into x. if operation is an even number, use floating point division to divide y into x. if none of the other tests on operation apply, multiply x and y. note: operation can be negative or zero.

Consider the following statements: struct nametype{string first; string last; }; struct coursetype{string name; int callnum; int credits; char grade; }; struct studenttype{nametype name; double gpa; coursetype course; }; studenttype student; studenttype classlist[100]; coursetype course; nametype name; mark the following statements as valid or invalid. if a statement is invalid, explain why. a.) student. course. callnum = "csc230"; b.) cin > > student. name; c.) classlist[0] = name; d.) classlist[1].gpa = 3.45; e.) name = classlist[15].name; f.) student. name = name; g.) cout < < classlist[10] < < endl; h.) for (int j = 0; j < 100; j++)classlist[j].name = name; i.) classlist. course. credits = 3; j.) course = studenttype. course;
