实验及习题指导手册
prints the time in standard format during each iteration of the loop to illustrate that the tick
member function works correctly. Be sure to test the following cases:
z Incrementing into the next minute.
z Incrementing into the next hour.
z Incrementing into the next day (i.e., 11:59:59 PM to 12:00:00 AM).
注意以下额外要求：
Then change the tick member function to a friend function of class Time, which will access the
private data member of Time directly. You should get the same output as above.
friend void tick(Time &t); // increment one second

DescriptionoftheProblem
(HugeInteger Class) Create a class HugeInteger that uses a 40-element array of digits
to store integers as large as 40 digits each. Provide member functions:
(a) Constructor, destructor
(b) input, output, add and substract
(c) For comparing HugeInteger objects, provide functions isEqualTo, isNotEqualTo,
isGreaterThan, isLessThan, isGreaterThanOrEqualTo and
isLessThanOrEqualToeach of these is a "predicate" function that simply returns
TRue if the relationship holds between the two HugeIntegers and returns false if
the relationship does not hold. Also, provide a predicate function isZero.
If you feel ambitious, provide member functions multiply, divide and modulus.
注：不考虑负数情况，即 hugeintA-hugeintB 确保 hugeintA 大于 hugeintB；而
hugeintA+hugeintB，确保不溢出
