- 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; }arrow_forward17. Math Tutor Write a program that can be used as a math tutor for a young student. The program should display two random numbers to be added, such as 247 +129 The program should then pause while the student works on the problem. When the student is ready to check the answer, he or she can press a key and the program will display the correct solution: 247 +129 376arrow_forwardInstructions The program in the Programming Example: Fibonacci Number does not check: Whether the first number entered by the user is less than or equal to the second number and whether both the numbers are nonnegative. Whether the user entered a valid value for the position of the desired number in the Fibonacci sequence. Rewrite that program so that it checks for these things. NOTES: If an invalid number is entered for case 1 above, prompt the user to enter both numbers again. If an invalid number is entered for case 2, prompt the user to enter a value until a valid value is entered. the code: #include <iostream> using namespace std; int main() { //Declare variables int previous1; int previous2; int current; int counter; int nthFibonacci; cout << "Enter the first two Fibonacci numbers: "; //Step 1 cin >> previous1 >> previous2; //Step 2 cout << endl; //verify the first two values if(previous1<0 && previous2>0)…arrow_forward
- Hailstone sequence Given a positive integer n, the following rules will always create a sequence that ends with 1, called the hailstone sequence: If n is even, divide it by 2 If n is odd, multiply it by 3 and add 1 (i.e. 3n +1) Continue until n is 1 Write a program that reads an integer as input and prints the hailstone sequence starting with the integer entered. Format the output so that ten integers, each separated by a tab character (\t), are printed per line. The output format can be achieved as follows:System.out.print(n + "\t"); Ex: If the input is: in javaarrow_forwardFinancial application: compute future apartment rent) Suppose that the rent for an apartment is $1000 thisyear and increases 3% every year.

- PART I: Functions – Math Test Write the Flowchart and Python code for the following programming problem based on the pseudocode below. Write a program that will allow a student to enter their name and then ask them to solve 10 mathematical equations. The program should display two random numbers that are to be added, such as: 247 + 129 The program should allow the student to enter the answer. The program should then display whether the answer was right or wrong, and accumulate the correct values. After the 10 questions are asked, calculate the average correct. Then display the student name, the number correct, and the average correct in both decimal and percentage format. In addition to any system functions you may use, you might consider the following functions: A function that allows the student to enter their name. A function that gets two random numbers, anywhere from 1 to 500. A function that displays the equation and asks the user to enter their answer. A function that…arrow_forwardQuestion Write the pseudocode for a program that will process attendance records of CA students. The students attend college five days a week. Input values are the student's name, number, and the time in and time out for each day of the week (i.e. five different times in and times out must be input). If a student attends college more than 36 hours in a week, a congratulatory message is printed. If a student attends college less than 30 hours in a week, a warning message is printed. The output for each student is the name, hours, and the appropriate attendance message. Processing continues until a student number of zero is input. Assume that students always check in and out on the hour. Therefore, timeln and timeOut will be integer variables (i.e. they represent whole hours, and minutes are ignored).arrow_forwardPeriodic compounding The total accumulated value, including the principal sum P, is given by the formula: where: nt A = P(1 + 1) "² n A is the final amount Accumulated Value P is the original principal sum r is the nominal annual interest rate n is the compounding frequency t is the overall length of time the interest is applied (expressed using the same time units as r, usually years). Using the above formula write a program that will display the following table. Principal-Value | Times-Interest-Compunded | Annual-Int-Rate | Term | Accumulated-Value 1000 6.00% 10 3.20% 15 2000 3000 9.25% 10 2 ** 3 8 | You must use exponent operator to compute P Exponent Operator in Python is ** Examples m=3 n=2 p= m **n (https://en.wikipedia.org/wiki/Compound_interest) 1 2 4 base = 2 exp = 4 a = base ** exp print(a) 16 print("Solving the exponent, we get Solving the exponent, we get 9 ,p ) 1790.85 3219.89 7486.33arrow_forward
