8. Cookie Calories A bag of cookies holds 40 cookies. The calorie information on the bag claims that there are 10 servings in the bag and that a serving equals 300 calories. Write a program that lets the user enter the number of cookies he or she actually ate and then reports the number of total calories consumed.

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; }
Question # 7: Write a program that inputs a sentence from the user and counts the number of words and characters in the sentence.
Computer Fundamentals and Programming 2 Write a program that determines a student’s grade. The program will accept 3 scores and computes the average score. Determine the grade based on the following rules: - If the average score is equal or greater than 90, the grade is A. - If the average score is greater than or equal to 70 and less than 90, the grade is B. - If the average score is greater than or equal to 50 and less than 70, the grade is C. - If the average score is less than 50, the grade is F.

Programming Exercise 10 in Chapter 6 asks you find the mean and standard deviation of five numbers. Extend this programming exercise to find the mean and standard deviation of up to 100 numbers. Suppose that the mean (average) of n numbers x1, x2, . . ., xn is x. Then the standard deviation of these numbers is:S=sqrt(((x1-x)^2+(x2-x)^2+...+(xi-x)^2+...+(xn-x)^2)/n)
C ++ Lab Cross Out Write a program that will ask for a sentence and letters to cross out. It should then print the sentence with the given letters changed to ‘X’ and it should say how many letters were crossed out. It should work regardless of case.
Net Salary Calculator (Toy Problem)Write a program whose major task is to calculate an individual’s Net Salary by getting the inputs of basic salary and benefits. Calculate the payee (i.e. Tax), NHIFDeductions, NSSFDeductions, gross salary, and net salary.
Consider records of employees each consists of employee's first name (string), number of hours worked (int)and hourly rate in Bahraini Dinar BD. (double).Write a program that reads from the user multiple records for multiple employees and displays the following onscreen:(a) the salary for each employee (Salary = Hours Worked x Hourly rate.)(b) the number of employees(c) the highest salary with employee name.Reading records of employees should stop when the user enter `stop' for the employee name. Sample I/O of theprogram is shown in the example below.
Problem: Feed Nibble Monster Till Full Write a program that generates a number in [0, 500] at the beginning -- this corresponds to how hungry the monster is -- and keeps asking the user to feed the monster until that number falls to zero. Each time the user feeds the monster a nibble, hunger decreases by the decimal value of the character (i.e. if the user feeds 'A' hunger decreases by 65). But when the user feeds the monster some character that isn't a nibble, the hunger increases by the decimal value of the character (since puking depletes energy). Use while loop. Sample runs: Notice the loop exits after one iteration, because hunger was very low and one nibble made the monster full: Notice hunger increasing after non-nibble (pink highlight): Notice that the program just keeps going when the user feeds the monster only non-nibbles. Do you think the program will keep running forever if the user never gives the monster nibbles?
Singular to Plural. Create a program that accepts a word in singular, and produces the corresponding plural. Use the following rules: a. If the word end in ‑s, -ss, -sh, -ch, -x, or –z, then add –es to the word. For example, the plural of tax is taxes b. If the word ends in -fe, then replace the ending with –ves. For example, the plural of wolf is wolves c. If the word ends in y and the previous letter is a vowel, then add –s to the word. For example, the plural of boy is boys d. If the word ends in y and the previous letter is a consonant, then change the –y ending with –ies. For example, the plural of city is cities e. If the word does not meet the criteria above, then add –s to it.
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.)
26. A room has one door, two windows, and a built-in bookshelf and it needs to be painted. Suppose that one gallon of paint can paint 120 square feet. Write a program that prompts the user to input the lengths and widths of the door, each window, the bookshelf; and the length, width, and height of the room (in feet). The program outputs the amount of paint needed to paint the walls of the room.
French Articles: French country names are feminine when they end with the letter e, masculine otherwise, except for the following which are masculine even though they end with e: le Belize le Cambodge le Mexique le Mozambique le Zaïre le Zimbabwe Write a program that reads the French name of a country and adds the article: le for masculine or la for feminine, such as le Canada or la Belgique. However, if the country name starts with a vowel, use l’; for example, l’Afghanistan. For the following plural country names, use les: les Etats-Unis les Pays-Bas
