Step $3$ File IO please do main.cpp Big decimal.cpp and the rest

Make a change to your BigDecimal class to add the following functions $($methods$)$

int wholeNumber$()-$ Returns only the whole number portion of the decimal

number as an int

double fraction$()-$ Returns the fractional portion of the number as double

File IO

Attached at this link is a text file called Numbers.txt $$ that contains several numbers.

You are to read in each of these numbers and store them in your BigDecimal class.

Basically you are going to need a BigDecimal class for each number that is in the file.

Store each BigDecimal in some kind of container like a vector or an ArrayList.

Once you have all of the numbers loaded use a loop to write out all of the numbers

into two separate text files. One file called wholeNumbers.txt will hold the whole

number portion of the number. The other file call fraction.txt will hold the fractional

portion of the number. Make sure you include the decimal point.

Open each of the files in Notepad and make sure that you have one number per line.
