Write a program to help a local restaurant automate its breakfast billing system. The program should show the customer the different breakfast items offered by the restaurant.

Write a program to help a local restaurant automate its breakfast billing system. The program should calculate and print the bill. Assume that the restaurant offers the following breakfast items (the price of each item is shown to the right of the item):

Plain Egg                      $1.45
Bacon and Egg$2.45
Muffin                         $0.99
French Toast$1.99
Fruit Basket                   $2.49
Cereal$0.69
Coffee                         $0.50
Tea$0.75

Use an array menuList of type menuItemType, as defined in Programming Exercise 3. Your program must contain at least the following functions:

• Function getData: This function loads the data into the array menuList.
• Function showMenu: This function shows the different items offered by the restaurant and tells the user how to select the items.
• Function printCheck: This function calculates and prints the check. (Note that the billing amount should include a 5% tax.) A sample output is:

Welcome to Johnny's Restaurant
Bacon and Egg              $2.45
Muffin$0.99
Coffee                     $0.50
Tax$0.20
Amount Due                 $4.14

Format your output with two decimal places. The name of each item in the output must be left justified. You may assume that the user selects only one item of a particular type.

Write a program to help a local stock trading company automate its systems. The company invests only in the stock market. At the end of each trading day, the company would like to generate and post the listing of its stocks so that investors can see how their holdings performed that day. We assume that the company invests in, say, 10 different stocks. The desired output is to produce two listings, one sorted by stock symbol and another sorted by percent gain from highest to lowest.

The input data is provided in a file in the following format:

symbol openingPrice closingPrice todayHigh todayLow
prevClose volume

For example, the sample data is:

MSMT 112.50 115.75 116.50 111.75 113.50 6723823
CBA 67.50 75.50 78.75 67.50 65.75 378233
.
.
.

The first line indicates that the stock symbol is MSMT, today’s opening price was 112.50, the closing price was 115.75, today’s high price was 116.50, today’s low price was 111.75, yesterday’s closing price was 113.50, and the number of shares currently being held is 6723823.

The listing sorted by stock symbols must be of the following form:

********* First Investor's Heaven **********
********* Financial Report **********
Stock Today Previous Percent
Symbol      Open     Close    High      Low      Close    Gain    Volume
------      -----    -----    -----     -----  --------  -------  ------
   ABC      123.45   130.95   132.00   125.00   120.50   8.67%    10000
  AOLK       80.00    75.00    82.00    74.00    83.00  -9.64%     5000
  CSCO      100.00   102.00   105.00    98.00   101.00   0.99%    25000
   IBD       68.00    71.00    72.00    67.00    75.00  -5.33%    15000
  MSET      120.00   140.00   145.00   140.00   115.00  21.74%    30920
Closing Assets: $9628300.00

Develop this programming exercise in two steps. In the first step (part a), design and implement a stock object. In the second step (part b), design and implement an object to maintain a list of stocks.

a.
Design and implement the stock object. Call the class that captures the various characteristics of a stock object stockType.

The main components of a stock are the stock symbol, stock price, and number of shares. Moreover, we need to output the opening price, closing price, high price, low price, previous price, and the percent gain/loss for the day. These are also all the characteristics of a stock. Therefore, the stock object should store all this information.

Perform the following operations on each stock object:

1. Set the stock information.
2. Print the stock information.
3. Show the different prices.
4. Calculate and print the percent gain/loss.
5. Show the number of shares.
   1. The natural ordering of the stock list is by stock symbol. Overload the relational operators to compare two stock objects by their symbols.
   2. Overload the insertion operator, <<, for easy output.
   3. Because the data is stored in a file, overload the stream extraction operator, >>, for easy input.

For example, suppose infile is an ifstream object and the input file was opened using the object infile. Further suppose that myStock is a stock object. Then, the statement:

infile >> myStock;

reads the data from the input file and stores it in the object myStock. (Note that this statement reads and stores the data in the relevant components of myStock.)

b.
Now that you have designed and implemented the class stockType to implement a stock object in a program, it is time to create a list of stock objects.

Let us call the class to implement a list of stock objects stockListType.

The class stockListType must be derived from the class listType, which you designed and implemented in the previous exercise. However, the class stockListType is a very specific class, designed to create a list of stock objects. Therefore, the class stockListType is no longer a template.

Add and/or overwrite the operations of the class listType to implement the necessary operations on a stock list. The following statement derives the class stockListType from the class listType.

class stockListType: public listType<stockType>
{
    member list
};

The member variables to hold the list elements, the length of the list, and the max listSize were declared as protected in the class listType. Therefore, these members can be directly accessed in the class stockListType.

Because the company also requires you to produce the list ordered by the percent gain/loss, you need to sort the stock list by this component. However, you are not to physically sort the list by the component percent gain/loss. Instead, you will provide a logical ordering with respect to this component.

To do so, add a member variable, an array, to hold the indices of the stock list ordered by the component percent gain/loss. Call this array sortIndicesGainLoss. When printing the list ordered by the component percent gain/loss, use the array sortIndicesGainLoss to print the list. The elements of the array sortIndicesGainLoss will tell which component of the stock list to print next.

c.
Write a program that uses these two classes to automate the company’s analysis of stock data.

Consider the definition of the function main:

int main()
{
    int x, y;
    char z;
    double rate, hours;
    double amount;
    .
    .
    .
}

The variables x, y, z, rate, and hours referred to in items a through f below are the variables of the function main. Each of the functions described must have the appropriate parameters to access these variables. Write the given definition:

• Write the definition of the function funcOne that prompts the user to input a number. The function then changes the value of x by assigning the value of the expression two times the (old) value of x plus the value of y minus the value entered by the user.

Consider the following function main:

int main()
{
    int inStock[10][4];
    int alpha[20];
    int beta[20];
    int gamma[4] = {11, 13, 15, 17};
    int delta[10] = {3, 5, 2, 6, 10, 9, 7, 11, 1, 8};
    .
    .
    .
}

1. Write the definition of the function setZero that initializes any onedimensional array of type int to 0.
2. Write the definition of the function inputArray that prompts the user to input 20 numbers and stores the numbers into alpha.
3. Write the definition of the function doubleArray that initializes the elements of beta to two times the corresponding elements in alpha. Make sure that you prevent the function from modifying the elements of alpha.
4. Write the definition of the function copyGamma that sets the elements of the first row of inStock to gamma and the remaining rows of inStock to three times the previous row of inStock. Make sure that you prevent the function from modifying the elements of gamma.
5. Write the definition of the function copyAlphaBeta that stores alpha into the first five rows of inStock and beta into the last five rows of inStock. Make sure that you prevent the function from modifying the elements of alpha and beta.
6. Write the definition of the function printArray that prints any onedimensional array of type int. Print 15 elements per line.
7. Write the definition of the function setInStock that prompts the user to input the elements for the first column of inStock. The function should then set the elements in the remaining columns to two times the corresponding element in the previous column, minus the corresponding element in delta.
8. Write C++ statements that call each of the functions in parts a through g.
9. Write a C++ program that tests the function main and the functions discussed in parts a through g. (Add additional functions, such as printing a two-dimensional array, as needed.)

Consider the following function main:

int main()
{
    int alpha[20];
    int beta[20];
    int matrix[10][4];
    .
    .
    .
}

• Write the definition of the function inputArray that prompts the user to input 20 numbers and stores the numbers into alpha.

Write a program that reads in a line consisting of a student’s name, Social Security number, user ID, and password. The program outputs the string in which all the digits of the Social Security number and all the characters in the password are replaced by x. (The Social Security number is in the form 000-00-0000, and the user ID and the password do not contain any spaces.) Your program should not use the operator [] to access a string element. Use the appropriate functions described in Table 7-1.
