(Huge Integer Class) Create a class Huge Integer that uses a 40-element array of digits to store integers as large as 40 digits each. Provide member functions input, output, add and subtract. For comparing Huge Integer objects, provide functions isEqualTo, is NotEqualTo, isGreaterThan, isLessThan, isGreaterThanOrEqualTo and isLessThanOr qualTo—each of these is a “predicate” function that simply returns true if the relationship holds between the two Huge Integers and returns false if the relationship does not hold. Also, provide a predicate function is Zero. If you feel ambitious, provide member functions multiply, divide and modulus.
