Write a C$++$ program to find and if possible correct the errors written in an input file. The input file as shown below consists of first and last names of people as well as their birthdates on each line:

As you can see from the file, the day, month or year of the birthdate might be incorrectly entered. You are expected to discard the input if the day and year are incorrect, and try to correct the month. To correct the month, check the first $3$ characters, if it matches one of the $12$ months, correct it$.$ For example, if $$Sepsember$$ is entered, its first $3$ characters match $$September$,$ so correct it accordingly. Output all the correcty entered or corrected inputs onto another file as shown below:

In your program, implement the following classes using composition:

Your main program should input each line from the input file, and using exception handling, check the day, month and year. If exceptions are thrown, in your first catch routine, output an error message if day or year is incorrect. In your second catch, try to correct the month according to the first $3$ characters. If you can correct the month, output the corrected information onto the output file. A sample output of the catch routines will be as follows:

Hints:

$1.$ To check the first $3$ characters of a string, you can use the substr$()$ function in the string header file.

st$.$substr$($x$,$n$)$: returns n characters from the string st starting from position x$.$

$2.$ To make your job easier, you may think about putting the $12$ months into an array of strings.

IMPORTANT NOTES:

$$ Cheating will NOT be tolerated. Special software will be used to verify if the submitted homework is your original work or copied from someone$/$somewhere else. If any case of cheating is detected, at any time, you will get ZERO from your homework.

$$ You should upload your homework file to the Moodle system.

$$ The name of your homework file should be $$StudentID$\_$HwNumber.cpp$,$ for example: $"11122233\_$hw$3.$cpp$"$
