For each of the following exercises, you may choose to write a console-based or GUI application, or both. Write a program named TestScoreList that accepts eight int values representing student test scores. Display each of the values along with a message that indicates how far it is from the average.

18. Tom and Jerry opened a new lawn service. They provide three types of services: mowing, fertilizing, and planting trees. The cost of mowing is $35.00 per 5,000 square yards, fertilizing is $30.00 per application, and planting a tree is $50.00. Write an algorithm that prompts the user to enter the area of the lawn, the number of fertilizing applications, and the number of trees to be planted. The algorithm then determines the billing amount. (Assume that the user orders all three services.) (9)

(Data processing) A bank’s customer records are to be stored in a file and read into a set of arrays so that a customer’s record can be accessed randomly by account number. Create the file by entering five customer records, with each record consisting of an integer account number (starting with account number 1000), a first name (maximum of 10 characters), a last name (maximum of 15 characters), and a double-precision number for the account balance. After the file is created, write a C++ program that requests a user-input account number and displays the corresponding name and account balance from the file.

(Data processing) Write a C++ program that permits users to enter the following information about your small company’s 10 employees and then writes the information to a file: ID No. Sex (M/F) Hourly Wage Years with the Company

Why do you need to include function prototypes in a program that contains user-defined functions? (5)

The case problems in this section introduce two fictional businesses. Throughout this book, you will create increasingly complex classes for these businesses that use the newest concepts you have mastered in each chapter. Marshalls Murals is a company that paints interior and exterior murals for both business and residential customers. Write a program named MarshallsMotto2 that displays the company motto, which is Make your vision your view. Create a second program named MarshallsM0tt02 that displays the motto surrounded by a border composed of repeated Ms.

(Modify) Rewrite the following programs to conform to good programming practice and correct syntax: a. #include using namespace std; int main( ){ cout << “The time has come” ; return 0;} b. #include using namespace std; int main ( ){cout << “Newark is a city\n”;cout << “in New Jersey\n”; cout << “It is also a city\n” ; cout << “in Delaware\n” ; return 0;} c. #include using namespace std; int main() {cout << Reading a program\n”;cout << “is much easier\n” ; cout << “if a standard form for main is used\n” ; cout <<“and each statement is written\n”;cout << “on a line by itself\n” ; return 0;} d. #include using namespace std; int main ( ){ cout << “Every C++ program” ; cout <<“\nmust have one and only one” ; cout << “main function” ; cout << “\n The escape sequence of characters”) ; cout << “\nfor a newline can be placed anywhere” ; cout <<“\n in the message passed to cout” ; return 0;}

(Data processing) Your professor has asked you to write a C++ program that determines grades at the end of the semester. For each student, identified by an integer number between 1 and 60, four exam grades must be kept, and two final grade averages must be computed. The first grade average is simply the average of all four grades. The second grade average is computed by weighting the four grades as follows: The first grade gets a weight of 0.2, the second grade gets a weight of 0.3, the third grade gets a weight of 0.3, and the fourth grade gets a weight of 0.2. That is, the final grade is computed as follows: 0.2grade1+0.3grade2+0.3grade3+0.2grade4 Using this information, construct a 60-by-7 two-dimensional array, in which the first column is used for the student number, the next four columns for the grades, and the last two columns for the computed final grades. The program’s output should be a display of the data in the completed array. For testing purposes, the professor has provided the following data:
