Your BigDecimal class should have the following constructors

BigDecimal$()-$ default constructor should simply set your container to three Char objects that contain the values $\text{'}0\text{'}\text{'}.\text{'}\text{'}0\text{'}$

BigDecimal$($String value$)-$ This constructor will parse the string taking each digit, putting it into a new Char 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 the multiply and divide 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
