objects that contain the values $\text{'}0\text{'}.\text{'}0\text{'}$

BigDecimal$($String value$)-$ This constructor will parse the string,g taking each digit,

putting it into a new Cha,r and adding the Char to the container.

Your BigDecimal class should also contain the following mutators

void setValue$($char ch$)-$ A char that contains a digit

void setValue$($String value$)-$ This does the same as the overloaded constructor that

takes a string

BigDecimal add$($BigDecimal$)-$ Adds the values together and returns the result as a

Big Decimal

BigDecimal sub$($BigDecimal$)-$ Subtracts the two values and returns the result as a

BigDecimal

Note: If you are using C$++,$ feel free to use the $+$ operator instead of the add function.

I am going to let you off the hook for multiplying and dividing, but it should be easy to

implement.

Accessors

double toDouble$()-$ Returns the value stored in the container as a double

String toString$()-$ Returns the value store in the container as a string

Char at$($int index $)-$ Returns the value at the particular index as a Char

Caveat:

If you are using C$++$ your container must hold pointers to the Char type. This means

when you push something back, you need to do the following:

v$.$push$\_$back$($new Char$(\text{'}$A$\text{'})$;

Java you will use references but the principle is the same. Simpy add a new Char to

whatever container you are using.

al$.$add$($new Char$(\text{'}$A$\text{'}))$;

Other requirement

Before adding anything to your container, you must determine if the value is actually a

digit. If it is not then simply stop processing characters at that point. You are also to

make sure that not more than one decimal is placed. Basically, I am asking you to have a

container that has a well$-$formed number

Step $3$ File $10$

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.

Step $4$ Exceptions

Create an exception class called CharException to be thrown in the setChar function

that takes an int as a parameter. You should check the range of the int to make sure it is

a valid readable character. Basically if the parameter is less than $32$ or greater than $127$

you want to throw a CharException with the message "Invalid Character".

Java:

Use inheritance to extend your class from Exception. Create a constructor that takes

the message to be set. You are going to have to call the super constructor to make sure

the message is set properly. Use the getMessage method to display the error message

you set. Here is a code example that shows main and the output: $AB$

A In Hex: $41$

A In Decimal $65$

Try to set $140$ as character

Invalid Character

Press any key to continue $...$

Finally

Create a BigDecimalException class that is derived from the CharException class. You

should throw this exception anytime that a character is being set that is not a valid

character $($a digit or a decimal$).$ You should also throw this exception if more than one

decimal is being set.

At this point, I am not going to give you many specifics on how to implement this. I will

only say that you are to use inheritance. No matter how you implement this class,

please have good reasoning for doing so$.$ It is time for all of us to start using what we

have learned to formulate our own ideas.

Important:

For this assignment I expect that you will use good coding practices. This means that

whenever possible you should create one code path. Having code duplications will be

frowned upon and may result in a point reduction in your grade.

C$++$ please show me step by step I wanna learn I am new to this Also show me how to fill up i know how to create the files that are required like the char.h and the other ones they ask what I am having trouble with is filling them up with there right codes
