Implement this C program using at least three arrays to store the interest, principle and balance after each payment respectively. For example, interest[0] stores the paid interest in the first payment. Besides, please use three pointers to visit the element in the three arrays separately. Name this C program as loanCalcPtr.c .

Appendix:
1. Calculating the monthly payment.
(Note: The following instruction is from http://www.vertex42.com/
ExcelArticles/amortization-calculation.html)
The formula for calculating the payment amount i shown below.
where
r(1+r)^
(1+r)n-1
A = B-
A = payment Amount per period (monthly payment)
B = initial Balance (loan amount)
r = interest rate per period
n = total number of payments or periods
Example 1: What would the monthly payment be on a 5-year, $20,000 car loan with a
nominal 7.5% annual interest rate?
B = $20,000
r = 7.5% per year / 12 months = 0.625%= 0.00625 per period
n = 5 years * 12 months = 60 total periods
0.00625 (1+0.00625)60
A = 20000 *
= 400.76
(1+0.00625 )60-1
2. Calculating the Principal(P), Interest(INT) and Balance(B) for each
payment.
The formula is shown below.
INT(n) = B(n-1) *r;
P(n) = A
INT(n);
B(n)= B(n-1) - P(n);
Where INT (n), P (n) and B(n) are the paid principal, paid interest and new balance for the
nth payment. And B (0) means the loan amount.

Write a C program to calculate monthly payment and print a table of payment schedule for a
fixed rate loan, which performs a similar task as in the link below:
http://www.bankrate.com/calculators/mortgages/loan-calculator.aspx
In this C program, the input and output are defined as following:
The attached screenshot below shows a sample of the output.
Yuans-MacBook-Pro:PC yuanlong$ ./loanCalc
Enter amount of loan $500
Enter Interest rate per year : % 7.5
Enter number of payments : 5
UNH
Input: amount of loan, interest rate per year and number of payments
Montly payment should be 101.88
45
Output: a table of amortization schedule (also called payment schedule) containing
payment number, monthly payment, principal paid, interest paid and new balance at each
row.
Note:
Payment
$101.88
$101.88
$101.88
$101.88
$101.88
=====AMORTIZATION SCHEDULE==
Principal
$98.76
$99.38
$100.00
$100.62
$101.25
Interest
$3.12
$2.51
$1.89
$1.26
$0.63
Balance
$401.24
$301.87
$201.87
$101.25
$0.00
monthly payments are equal. The way to calculate monthly payment and other values for
each row are provided in Appendix.
The C program can be implemented within 80 lines of code. If your program is longer
than 80 lines, you may need to think about how to simplify your program.
Hint: To print out a percentage %, please use %%. You may need to use C math library to
calculate the powers of numbers. To compile a C program using math library, you must add
option Im at the end of the cc command to link math library. E.g. gcc -o test test.c -lm
