- When you borrow money to buy a house, a car, or for some other purpose, you repay the loan by making periodic payments over a certain period of time. Of course, the lending company will charge interest on the loan. Every periodic payment consists of the interest on the loan and the payment toward the principal amount. To be specific, suppose that you borrow $1,000 at an interest rate of 7.2% per year and the payments are monthly. Suppose that your monthly payment is $25. Now, the interest is 7.2% per year and the payments are monthly, so the interest rate per month is 7.2/12 = 0.6%. The first months interest on $1,000 is 1000 0.006 = 6. Because the payment is $25 and the interest for the first month is $6, the payment toward the principal amount is 25 6 = 19. This means after making the first payment, the loan amount is 1,000 19 = 981. For the second payment, the interest is calculated on $981. So the interest for the second month is 981 0.006 = 5.886, that is, approximately $5.89. This implies that the payment toward the principal is 25 5.89 = 19.11 and the remaining balance after the second payment is 981 19.11 = 961.89. This process is repeated until the loan is paid. Write a program that accepts as input the loan amount, the interest rate per year, and the monthly payment. (Enter the interest rate as a percentage. For example, if the interest rate is 7.2% per year, then enter 7.2.) The program then outputs the number of months it would take to repay the loan. (Note that if the monthly payment is less than the first months interest, then after each payment, the loan amount will increase. In this case, the program must warn the borrower that the monthly payment is too low, and with this monthly payment, the loan amount could not be repaid.)arrow_forwardWhat is the value of each of the following Boolean expressions? 54 3=3 2+45 6==7 2+4=6 3+4==4+3 1!=2 2!=2 5==72 3+9=0arrow_forwardhow to do this in in C++ Language Zodiac Sign Identifier - Ask the user's birth month and birth day and return the corresponding Zodiac Sign he/she belongs: Evaluate the user's birth month and day by checking the following: If born from, Mar 21 to Apr 19 - Aries Apr 20 to May 20 - Taurus May 21 to Jun 20 - Gemini Jun 21 to Jul 22 - Cancer Jul 23 to Aug 22 - Leo Aug 23 to Sep 22 - Virgo Sep 23 to Oct 22 - Libra Oct 23 to Nov 21 - Scorpio Nov 22 to Dec 21 - Sagittarius Dec 22 to Jan 19 - Capricorn Jan 20 to Feb 18 - Aquarius Feb 19 to Mar 20 - Pisces Example: What is your month of birth? 1 - January (31 days) 2 - February (27 days, if Leap Year 28 days) 3 - March (31 days) 4 - April (30 days) 5 - May (31 days) 6 - June (30 days) 7 - July (31 days) 8 - August (31 days) 9 - September (30 days) 10 - October (31 days) 11 - November (30 days) 12 - December (31 days) Please enter your birth month: 8 Please enter day of your birth: 16 Please enter your year of birth: 1997 Your birthday is…arrow_forward

- Write a simple payroll program that will display employee’s information. Refer to the UMLClass Diagram for the names of the variable and method. This should be the sequence of theprogram upon execution:a. Prompt the user to input the name of the employee.b. Prompt the user to select between full time and part time by pressing either F (fulltime) or P (part time).c. If F is pressed, ask the user to type his monthly salary. Then, display his name andmonthly salaray.d. If P is pressed, ask the user to type his hourly rate and hours worked separated by aspace. Then display his name and wage.arrow_forwardInterest on a credit card’s unpaid balance is calculated using the average daily balance. Suppose that netBalance is the balance shown in the bill, payment is the payment made, d1 is the number of days in the billing cycle, and d2 is the number of days payment is made before billing cycle. Then, the average daily balance is: averageDailyBalance = (netBalance * d1 - payment * d2) / d1. The interest on the unpaid balance is: interest = averageDailyBalance * interestRate where interestRate is the interest rate per month. Write a program that accepts as input netBalance, payment, d1, d2, and interestRate. The program outputs the interest. Format your output to two decimal places. Analyze and design this program.
