Please help implement a '+' operator that takes two intervals and takes the smallest interval and then the largest for the end. Example: Interval(4, 6) + Interval(5, 8) equals to Interval(4, 8), and Interval(4, 6) + Interval(7, 8) equals to Interval(4, 8). !!!!!!!This one below here is the .cpp file i need to implement, only file i can change. I worked on it but i keep getting an error which is shown in the image #include #include "interval.h" using namespace std; Interval::Interval(int lower_bound, int upper_bound) { low = lower_bound; high = upper_bound; } void Interval::print(ostream& out) const { out << "(" << low << ", " << high << ")" << endl; } Interval Interval::operator+(const Interval &other) const { int temp_low, temp_high; if(this->low <= other.low) { temp_low = this->low; } else { temp_low=other.low; } if(this->high >= other.high) { temp_high = this->high; } else { temp_high=other.high; } return Interval(temp_low,temp_high);
