Summary
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.
Instructions
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 <iostream>#include <iomanip> using namespace std; int main(){ double cost; double area; double bagSize; cout << fixed << showpoint << setprecision(2); cout << "Enter the amount of fertilizer, in pounds, " <<…

It then calculates the size of the payments and the total paid over the life of the loan. (Note that the user enters percent annual interest rate while the formula uses decimal interest per year! Pay attention to variable names.) Remember to test your program by trying all different possible combinations of input. When testing your program, be sure to enter some incorrect data, such as text instead of numbers, decimal percentage rate instead of integer percentage rate, and unfilled fields to witness how the program behaves. Your program does not have to correct for bad input, but it should accept interest as percent per year. Note the use of really…arrow_forward
