1. Design a class based on a modified Customer Structure. Use private and public definitions.

2. Create class methods (Setters and Getters) that load the data values. The Setter methods will validate the input data based on the criteria below and load the data into the class if valid.

       For character arrays, the data must be within the specified data size. (See #3 below)

   For zipCode, the number must be between 0 and 99999.

       City and State need to be converted and stored in uppercase.

To get started loading the c-strings.

Getters

The book does not seem to provide a good example of what a (getter) method that returns a char array should look like. Section 9.9 is very close but uses string as examples instead of c-strings.

The best approach is to return a pointer to the c-string- Described as below:

   char* getName(); // declaration - also known as prototype

// Customer is my Class name 

char* Customer::getName() {  // defined member function - Return a pointer to the c-string
    return name;
}

cout << YOUR_INSTANCE_HERE.getName() << endl;

Setters

As for creating a setter method - you can define unsized char arrays in the method header

bool Customer::setName(char inputName[]) {

// code here..

}

3. Write a program that will allow me to enter data for the class and create and call a method that displays the data for the class.

During the input process, pass the input data to the setter method and confirm that the data entered is valid based on the class method return value. If not valid,prompt for me to re-enter the data until it does pass the class method's validation.(A do-while loop works well for this situation) I only need to enter the data for 1 instance of the class. The best way to do this is for the setter methods to return bool instead of void. If the data is valid, return true. Otherwise return false.

There is no need to loop for multiple instances of the object. Do not use cin statements inside the class method definitions.

Below is the original structure to use to create your class definition.

const int NAME_SIZE = 20;
const int STREET_SIZE = 30;
const int CITY_SIZE = 20;
const int STATE_CODE_SIZE = 3;

struct Customer {
    long customerNumber;
    char name[NAME_SIZE];
    char streetAddress_1[STREET_SIZE];
    char streetAddress_2[STREET_SIZE];
    char city[CITY_SIZE];
    char state[STATE_CODE_SIZE];
    int zipCode;

};

Hints: The const variables need to be defined outside of the class definition.

          All access to the data in the class must use public methods that you define. DO NOT DIRECTLY ACCESS the customer data items.

          The class level input methods should return a boolean to confirm the data was loaded and passed any size or data ranges. The customerNumber setter does not need to return a value - It can be a void setter.

          Set the customerNumber to 1 via the code - not user input. There is no input loop so only 1 set of customer's data is to be entered.

Write a python program to evaluate polynomials in general and test it on the following polynomial: ? 4 − 3? 3 − 39? 2 + 47? + 90 = 0

a) Develop and test a function named polyCalc() that evaluates a polynomial at a given value of the variable. The function receives two arguments: a list of the polynomial coefficients, and the value of the variable. It returns the result of the evaluation as a float. Use your function to evaluate the polynomial at ? = -5.4, -5.2, -1.2, -1.0, 2.0, 2.2, 7.2 and 7.4. What do you conclude about the solutions to the equation above?

b) Write a second function named polySolve() that seeks a solution of the polynomial between two values of the variable where the function has changed sign. This function should receive the list of coefficients, the two values of the variable between which there is a solution. It should return the value of the variable at which a solution was found. This function may be based on an exhaustive search, a bisection search, or on Newton-Raphson’s method. Select a method with some justification.

A company which produces a single product has definite orders for this product over the next four quarters as follows:

The company ended the previous year with an inventory of 300 units, and the final quarter production level was 420 units. The company wishes to end this year with an inventory of at least 280 units.

It costs $30 per unit to increase the production level from one quarter to the next, and $56 per unit to decrease it. The cost of holding inventory from one quarter to the next is $40 per unit per quarter. No shortages are permitted. The company wishes to minimize the sum of production level change costs and inventory costs over the four quarter planning horizon.

Formulate (but do not solve) a model for this situation.

THREES ELECTRONICS COMPANY Threes Electronics is a mid-sized electronics manufacturer located in Santa Monica, California. The company president is Jack Tripper, who inherited the company. The company originally repaired radios and other household appliances when it was founded over 70 years ago. Over the years, the company has expanded, and it is now a reputable manufacturer of various specialty electronic items. One of the major revenue-producing items manufactured by Threes Electronic is a Personal Digital Assistant (PDA). Threes Electronics currently has one PDA model on the market and sales have been excellent. The PDA is a unique item in that it comes in a variety of tropical colors and is preprogrammed to play Jimmy Buffet music. However, as with any electronic item, technology changes rapidly, and the current PDA has limited features in comparison with newer models. Threes Electronic spent $750,000 to develop a prototype for a new PDA that has all the features of the existing one, but adds new features such as cell phone capability. The company has spent a further $200,000 for a marketing study to determine the expected sales figures for the new PDA. Threes Electronic can manufacture the new PDA for $86 each in variable costs. Fixed costs for the operation are estimated to run $3 million per year. The estimated sales volume is 70,000, 80,000, 100,000, 85,000, and 75,000 per each year for the next five years, respectively. The unit price of the new PDA will be $250. The necessary equipment can be purchased for $15 million and will be depreciated on a 7-year MACRS schedule. It is believed the value of the equipment in five years will be $3 million. Net working capital for the PDAs will be 20 percent of sales and will occur with the timing of the cash flows for the year (i.e., there is a no initial outlay for NWC). Changes in NWC will thus first occur in Year 1 with the first year’s sales. Threes Electronic has a 35 percent (federal & state) corporate tax rate. Threes Electronic plans to finance by a combination of 1/3 debt and 2/3 internal equity (i.e., retained earnings). The beta of the firm’s stock is 1.75. The firm uses a risk-free rate of 4% and the market risk premium of 7%. Threes has 15,000 9 percent semi-annual coupon bonds outstanding, $1,000 par value per bond, 15 years to maturity, selling for 108 percent of par. Threes Electronic can issue bonds for $5 ~ $6 million in the similar terms. Construct a project cash flow statement; estimate the cost of capital; and provide NPV, IRR, payback period (our target PB is 3 years) and profitability index of this project.

Teloxy Engineering has received a one-time contract to design and build 10,000 units of a new product. During the proposal process, management felt that the new product could be designed and manufactured at a low cost. One of the ingredients necessary to build the product was a small component that could be purchased for $60 in the marketplace, including quantity dis- counts. Accordingly, management budgeted $650,000 for the purchasing and handling of 10,000 components plus scrap.

During the design stage, your engineering team informs you that the final design will require a somewhat higher-grade component that sells for $72 with quantity discounts. The new price is substantially higher than you had budgeted for. This will create a cost overrun.

You meet with your manufacturing team to see if they can manufacture the component at a cheaper price than buying it from the outside. Your manufacturing team informs you that they can produce a maximum of 10,000 units, just enough to fulfill your contract. The setup cost will be $100,000 and the raw material cost is $40 per component. Since Teloxy has never manu- factured this product before, manufacturing expects the following defects:

Percent defective 0 10 20 30 40 Probability of 10 20 30 25 15

occurrence
All defective parts must be removed and repaired at a cost of $120 per part.

1. Using expected value, is it economically better to make or buy the component?
   
2. Strategically thinking, why might management opt for other than the most economical
   choice?
