Question

Write the implementation for the class declaration below.

class Range {

friend ostream & operator<<(ostream &, const Range & r); // e.g. [3,5]

public:

// initialize minimum to the smaller of mini,maxi and maximim to the bigger

Range(int mini, int maxi);

const int minimum, maximum;

bool isIn(int val) const; // return true if val in the interval [minimum, maximum]

};

Driver code is below.

int main() {

int mn, mx;

cin >> mn >> mx;

Range r(mn,mx);

cout << "The range is " << r.minimum << " to " << r.maximum << " inclusive." << endl;

for (int i = r.minimum-3; i <= r.maximum+3; i++)

cout << left << setw(4) << i

<< (r.isIn(i) ? " is " : " isn't")

<< " in " << r << endl;

return 0;

}

A sample run:

3 1

The range is 1 to 3 inclusive.

-2 isn't in [1,3]

-1 isn't in [1,3]

0 isn't in [1,3]

1 is in [1,3]

2 is in [1,3]

3 is in [1,3]

4 isn't in [1,3]

5 isn't in [1,3]

6 isn't in [1,3]

Press any key to continue . . .

class Range { friend ostream & operator mn >> mx; Range r(mn,mx); cout
