PROG$20799$: Data Structures and Algorithm Dev in C

Evaluation: $10$ points.

Change Calculator

Write a C program that calculates the change as follows:

$1.$ Prompt the user for the amount of purchase, use variable name moneyOwed.

$2.$ Prompt the user for the amount paid, use variable name moneyPaid.

$3.$ Calculate the change in details. Declare an integer array change$[]$ of size $5,$ where the $0$th item

is the number of dollars, the $1$st is the number of quarters, the $2$nd is the number of dimes, the

$3$rd is the number of nickels, and $4$th is the number of pennies. You must use a function called

calcChange, call it in main$()$ as calcChange$($moneyOwed$,$ moneyPaid, change$),$ to perform this

task.

$4.$ Print out the results.

Requirements:

$1.$ Follow the principle of modular design where all input$/$output statements must be in the main$()$

function.

$2.$ Define the calcChange function in a separate C file named changeUtil.c along with its header

file changeUtil.h$.$

$3.$ Report an error for negative numbers or zero input.

$4.$ Report an error if money paid is not enough.

$5.$ If error occurs, give the user another try.

$6.$ Your program should be reasonably optimized: use proper data types, minimize the code.

$7.$ Your program should have the following output $($sample data here$)$:

Evaluation:

Your assignment will be graded based on the following:

$1.$ The program runs without errors $($logic and syntax$).$

$2.$ Functional requirements of the assignment are properly$/$completely met.

$3.$ Formatting, comments, indentation and variable name conventions are adequately

followed.

Good luck! Prof: Abdullah A$.$
