Question
DO YOUR OWN CODING
4) Implement this C program by defining a structure for each payment. The structure
should have at least three members for the interest, principle and balance
separately. And store all the payments in a structure array (the max size of which
could be 100). Name this C program as loanCalcStruct.c .

Transcribed Image Text: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:
Input: amount of loan, interest rate per year and number of payments
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.
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
Montly payment should be 101.88

Transcribed Image Text:Note:
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 -Im

He used to collect, organize and analyze the data pertaining his business. He is planning to expand the business with the inclusion of 15 more cars. To monitor the business, he needs to put more effort on analyzing the data. The following are the data he used to collect from the business.

The computer ‘hides’ the treasure at a random location in a 10x10 matrix. The user guesses the location by entering a row and column values. The game ends when the user locates the treasure or the treasure value is less than or equal to zero. Guesses in the wrong location will provide clues such as a compass direction or number of squares horizontally or vertically to the treasure. Using the random number generator, display one of the following in the board where the player made their guess: U# Treasure is up ‘#’ on the vertical axis (where # represents an integer number). D# Treasure is down ‘#’ on the vertical axis (where # represents an integer number) || Treasure is in this row, not up or down from the guess location. -> Treasure is to the right. <- Treasure is to the left. -- Treasure is in the same column, not left or right. +$ Adds $50 to treasure and no $50 turn loss. -$ Subtracts…arrow_forwardtypedef char string[50]; struct a Tag { int a; }; // 1. indicate the data type returned by function Exam() Exam(struct a Tag *ptr) { float b; double C[ 10 ]; string s; } // Access the members of the structure variable indirectly via ptr // You are REQUIRED to use the structure pointer operator; see comments numbered 2 to 5. // 2. input the value of member a scanf("%d", ); // 3. assign 3.1416 as the value of member b = 3.1416; // 4. print the value of the last element of array C. printf("%lf\n", |); // 5. copy "Hello" into string s strcpy( return ptr; , "Hello");arrow_forward
