Assignments submitted after the due date will incur a grade penalty of three $(3)$ points per day after the

first day, and will not be accepted more than one $(1)$ week late.

Project #$3$ String manipulation and algorithm development $(2$ extra credit options$)$

Design and implement a computer based solution $($program$)$ that meets the following requirements:

$1.$ The program will prompt the user for a date in the format:

mm$/$dd$/$yyyy sample input: $01/15/2021$

$2.$ The program will convert the date entered into the following format:

Month day, year sample output: January $15,2021$

$3.$ The program will validate the input, and show an error message if the input is in the wrong

format, or a month or day is out of range, and prompt again.

$4.$ The program will loop to allow the user to enter another date.

$5.$ Required functions called from main and included in a header file:

a$.$ A string function that prompts for a date, validates the input format with error messages,

and returns a valid string, or re$-$prompts for a valid input.

b$.$ A void function that receives the valid string, tests the month $(1-12)$ and day $(1-28,30,31)$

for the proper range, converts the input string into the proper output format and displays it$.$

Consider using an array for the month names:

string months$[]=\{"$January$",$ "February", "March", "April", "May", "June",

"July", "August", "September", "October", "November", "December" $\}$;

Months with $30$ days $$ April, June, September, and November

Assignments submitted after the due date will incur a grade penalty of three $(3)$ points per day after the

first day, and will not be accepted more than one $(1)$ week late.

EXTRA CREDIT #$1(10$ Points$)$: Modify the output function to output red text for errors and green text

for success.

EXTRA CREDIT #$2(10$ Points$)$: Adjust the range for February to $29$ days if it is a leap year. A leap year is

evenly divisible by $4,$ except if it is evenly divisible by $100$ unless it is also evenly divisible by $400.$

Example: $1700,1800,$ and $1900$ were not leap years, but $1600$ and $2000$ were.

Grading will be based on meeting all of the lab requirements, adherence to programming standards,

operation and accurate output, and programming style including white space and indentation. The

grade penalty is three $(3)$ points for each standards violation or missing requirement.
