$20\mathrm{.}30$ LAB$*$: Program: Credit card debt $($Arrays$)$

Program Specifications Write a program to search three parallel arrays containing customer credit card debt information. Identify statistics such as the number of customer names that begin with $\text{'}$S$\text{'},$ the number of customers with no debt, and the number of customers that live in a specific state.

Note: This program is designed for incremental development. Complete each step and submit for grading before starting the next step. Only a portion of tests pass after each step but confirm progress.

Step $0.$ Review the starter code in main$().$ The number of requested customers is input $($integer$).$ A function is called that reads data from a text file and fills three parallel arrays with customer names, state of residence, and amount of credit card debt for each customer. Using a function is a convenient way to fill arrays with hundreds of elements. Functions and reading data from text files are described in other sections of the book.

Step $1.$ Input a debt limit $($integer$),$ first letter of customer's name $($char$),$ and state abbreviation $($string$).$ Note that the number of customers is already input during Step $0.$

Step $2(2$ pts$).$ Use a loop to process each element of the names and debt arrays to identify the customer with the highest debt. Output a report header, number of customers, and the person's name with the highest debt. Submit for grading to confirm two tests pass.

Ex: If input is:

$\backslash [$

$1000250\backslash$mathrm$\{$P$\}\backslash$mathrm$\{$LA$\}$

$\backslash ]$

the output is:

$```$

U$.$S$.$ Report

Customers: $1000$

Highest debt: Sullivan

$```$ Step $\backslash (\backslash$mathbf$\{3\}\backslash )(2$ pts$).$ Use a loop to process each element of the names array to count all customer names that begin with the specified letter. Ex: How many customer names begin with $\text{'}$B$\text{'}$ or $\text{'}$L$\text{'}?$ Output the number of customer names that start with the specified letter. Submit for grading to confirm four tests pass.

Ex: If input is:

$\backslash [$

$1000250\backslash$mathrm$\{$P$\}\backslash$mathrm$\{$TX$\}$

$\backslash ]$

the output is:

$```$

U$.$S$.$ Report

Customers: $1000$

Highest debt: Sullivan

Customer names that start with $\text{'}$P$\text{'}$: $57$

$```$

Step $\backslash (\backslash$mathbf$\{4\}\backslash )(2$ pts$).$ Use a loop to process each element of the names and debt arrays to count the number of customers that have debt higher than the specified debt limit and the number of customers that have no debt. Output all results. Submit for grading to confirm six tests pass.

Ex: If input is:

$\backslash [$

$2000250\backslash$mathrm$\{$P$\}\backslash$mathrm$\{$TX$\}$

$\backslash ]$

the output is:

$```$

U$.$S$.$ Report

Customers: $2000$

Highest debt: Sullivan

Customer names that start with $\text{'}$P$\text{'}$: $111$

Customers with debt over $$250$: $1562$

Customers debt free: $438$

$```$ Step $5(4$ pts$).$ Repeat steps $2-4$ for all customers living in the specified state. Output all results including a header for the state report. Submit for grading to confirm all tests pass.

Ex: If input is:

$\backslash [$

$80008000\backslash$mathrm$\{$~A$\}\backslash$mathrm$\{$CA$\}$

$\backslash ]$

the output is:

$```$

U$.$S$.$ Report

Customers: $8000$

Highest debt: Anderson

Customer names that start with $\text{'}$A$\text{'}$: $261$

Customers with debt over $$8000$: $2480$

Customers debt free: $1697$

CA Report

Customers: $851$

Highest debt: Duenas

Customer names that start with $\text{'}$A$\text{'}$: $38$

Customers with debt over $$8000$: $268$

Customers debt free: $176$
