Converting dollars to cents would enable you to practice your fundamental knowledge of programming. Loops, if conditions and a simple algorithm will be used.
Your task is to let the user input a dollar value (float), assuming that it can also accept extra cents (ex. $2.75), and convert it into an integer (in this case, if $2.75 = 275). After this, convert into coins with the sub-type of dollars: penny, nickel, dime and quarter. Use an algorithm that would divide the dollar value to the four coin types, and output few coins as possible.
The challenge: Try this without using any frameworks.
(EX. If you have $0.58, I would have 4 coins: 2 quarters, 0 dimes, 1 nickel and 3 pennies)
## User Stories
- [ ] User can enter a dollar value
- [ ] User can see the total cents from the converted dollar value
## Bonus features
- [ ] User can see how many were pennies, nickels, quarters and dimes from the total cents
In this challenge, you'd create a javascript validation script to validate the inputs entered by a user using RegEx.
You could always refer to the [Regular Expression Library](http://regexlib.com/(X(1)A(GijS7qxVy-6Gyc4cweUyFoK4ZvRn2WnlOe8SSKuq9sT7ps-2nbiTmZZMTCn_rFk4-mNoGnYL-DPU8pJhmNNOtkP-syqWE4WO_1aVt4bPa5nTsQPQe6VRAALnm6QW3YIWbYkVS78JFbZN39vmMI1UYiWlHXKwNMB99WjsZOn0qc_8dcN0unp2KMOBw0P__3OH0))/CheatSheet.aspx?AspxAutoDetectCookieSupport=1) for support
For this project, there'd be three required inputs for validation:
- The first would require the user to enter five (5) capital letters, six (6) symbols and two hyphens (-) in any order. This could be used as a password.
- The second which could be used as username would require the user to enter letters without spaces
- The third which could be used as email address would require the user to enter only email addresses on gmail (...@gmail.com).
## User Stories
- [ ] User should be notified of any invalid inputs by error messages displayed on the form.
- [ ] The submit button on the form would never be executed until all entries are validated.

A currency converter is used to convert an amount in one currency to its corresponding value in another currency using their current exchange rate, for example it can be used to calculate the value of 100 US Dollars in Euros. Current exchange rates are usually provided by banks and other financial service providers, they also (in some cases) offer free and paid APIs for developers to get current and historical exchange rates between two or more currencies.
## User Stories
- [ ] User can enter up to 9 digits to represent the amount to convert in a source input field
