4. During each summer, John and Jessica grow vegetables in their backyard and buy seeds and fertilizer from a local nursery. The nursery carries different types of vegetable fertilizers in various bag sizes. When buying a particular fertilizer, they want to know the price of the fertilizer per pound and the cost of fertilizing per square foot. The following program prompts the user to enter the size of the fertilizer bag, in pounds, the cost of the bag, and the area, in square feet, that can be covered by the bag. The program should output the desired result. However, the program contains logic errors. Find and correct the logic errors so that the program works properly. // Logic errors. #include #include using namespace std; int main() { double costs double area; double bagsize; cout > bagsize; cout > cost; cout > area; cout << endl; cout << "The cost of the fertilizer per pound is: $" << bagsize / cost << endl; cout << "The cost of fertilizing per square foot is: $" << area / cost << endl; return 0; }

25. Repeat Programming Exercise 24, but the wire is to be bent in the form of a circle. In this case, the user specifies the length of the wire and the program outputs the radius and area of the circle. (You may assume that . Also declare it as a named constant.)

(Program) Write a program to simulate the rolling of two dice. If the total of the two dice is 7 or 11, you win; otherwise, you lose. Embellish this program as much as you like with betting, different odds, different combinations for win or lose, stopping play when you have no money left or reach the house limit, displaying the dice, and so forth. (Hint: Calculate the dots showing on each die with theexpressiondots=(int)(6.0randomnumber+1), where random number is between 0 and 1.)

(Modify) a. Modify the program you wrote for Exercise 7 to provide the mass of a person as an output, given his or her weight as an input to the program. Use your program to determine the mass of a person who weighs 140 lbf on Earth. b. Modify the program written for Exercise 7a to also output the person’s weight on Mars and the moon. The pull of gravity on Mars is 12.54ft/sec2=3.728m/s2,andonthemoonis5.33ft/sec2=1.625m/s2.

(Misc. application) Four experiments are performed, and each experiment has six test results. The results for each experiment are given in the following list. Write a program using a nested loop to compute and display the average of the test results for each experiment. 1stexperimentresults:23.23116.92725.428.62ndexperimentresults:34.845.227.936.833.439.43rdexperimentresults:19.416.810.220.818.913.44thexperimentresults:36.93949.245.142.750.6

Pig Latin is a nonsense language. To create a word in pig Latin, you remove the first letter and then add the first letter and ay at the end of the word. For example, dog becomes ogday and cat becomes atcay. Write a program named PigLatin that allows the user to enter a word and displays the pig Latin version.

(Misc. application) a. Write a program that continuously requests a grade to be entered. If the grade is less than 0 or greater than 100, your program should print an appropriate message informing the user that an invalid grade has been entered; else, the grade should be added to a total. When a grade of 999 is entered, the program should exit the repetition loop and compute and display the average of the valid grades entered. b. Run the program written in Exercise 2a and verify the program by using appropriate test data.

Modify the Eggs program to create a new one named Eggslnteractive that prompts the user for and accepts a number of eggs for each chicken.

15. Write a program to implement and test the algorithm that you designed for Exercise 15 of Chapter 1. (You may assume that the value of . In your program, declare a named constant PI to store this value.)
