Assuming there are no deposits other than the original investment, the balance in a saving account after one year may be calculated as
Amount=Principal * (1+ Rate / T)T
principal -balance in the saving account,
Rate -the interest rate,
T - number of times the interest is compounded during a year.
Write a program that asks for :
the principal, the interest rate, and the number of times the interest is compounded. It should display a report similar to
Interest Rate: 4.25%
Times Compounded: 12
Principal: $ 1000.00
Interest: $ 43.34
Amount in Savings: $ 1043.34
(Science: calculating energy) Write a program that calculates the energy needed to heat water from an initial temperature to a final temperature. Your program should prompt the user to enter the amount of water in kilograms and the initial and final temperatures of the water. The formula to compute the energy is Q = M * (finalTemperature – initialTemperature) * 4184 where M is the weight of water in kilograms, temperatures are in degrees Celsius, and energy Q is measured in joules.
Celsius to Fahrenheit: Write a program that converts Celsius temperatures to Fahrenheit temperatures. The formula or algebraic equation is F = ?? / ?? * C + 32, where F is the Fahrenheit temperature, and C is the Celsius temperature.
Input: temperature in Celsius
Output: as shown below
Topic: arithmetic expressions, cin, cout, integer division
Note: Please notice that the input is an integer but the output contains decimal numbers with one decimal place.

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_forward
