Intervals Arithmetic Interval arithmetic operations can be defined on intervals as follows: [a, b] + [c, d] = [a+c, b+d). [a, b] - [c, d] = [a-d, b-c]. [a, b] * [c, d] = [min(ac, ad, bc, bd), max(ac, ad, bc, bd)] , [a, b]/[c, d] = [min(a/d, alc, bld, ble), max(ald, alc, bld, b/c)] only if oi (c,d). Write the class Interval that has lower and upper of type double as data members, set, get, print, and constructor as member functions. Overload the post increment operator ++ (add 1 to both boundaries of the interval), and the += operator as members of the class, and overload the >>, > first >> second: cout
