Homework SourseWrite a modular program that calculates the total amount of
Write a modular program that calculates the total amount of interest earned for a group of bank accounts. The user should be allowed to specify the number of bank accounts. The amount of interest earned on a single account can be calculated by multiplying the account balance by the percent interest. Use the information in the table below to calculate the interest on an account.
Type of Account
Account Balance
Percent Interest
Checking
< $100
0
Checking
$100 - $1,000
.001
Checking
> $1,000
.002
Savings
<= $100
0
Savings
> $100
.015
Your program must use parallel arrays to store the information about the bank accounts – type of account (string) and balance (floating point). These arrays must NOT be declared globally.
Prompt the user for the type of account and the account balance. Use a menu to prompt the user for the type of account rather than letting them type in checking or savings.
Validate the user\'s input for account balance so that values less than 0 are not accepted.
Once the required information for all the bank accounts has been entered into arrays, then calculate the interest earned for each bank account storing the results in another parallel array – interest (floating point).
Use global constants for the percent interest.
Once the interest earned on each of the accounts has been calculated and stored in an array, then calculate and display the total amount of interest earned on all the accounts.
Dollar amounts should be properly formatted.
NOTE: Make sure your modular program includes some functions that accept input and return values.
| Type of Account | Account Balance | Percent Interest |
| Checking | < $100 | 0 |
| Checking | $100 - $1,000 | .001 |
| Checking | > $1,000 | .002 |
| Savings | <= $100 | 0 |
| Savings | > $100 | .015 |
