As part of a program that will be doing computations on various geometric objects, a programmer has submitted the following class declaration for approval. struct Line { // Provide access to the endpoints Point p1; Point p2; // Create a line segment Line() {}// Create a line segment with the given endpoints Line (Point endPoint1, Point endPoint2); // For a given x value, what is the corresponding value of // y along this line segment? (Returns std::DBL_MAX if no// such x exists or if x is not unique.)double x(double y) const;// Returns true if these line segments intersect at a point that lies// at or between the endpoint of each segment. bool crossesSegment (const Line& segment) const;// Returns true if p lies along this line segment (and at or// between the endpoints). bool contains (Point p) const;};ostream& operator<< (ostream& out, Line& line);Based upon this information, which of the C++ checklist items appear to be in violation?Redundant or generalizable functionsMeaningful namesUndocumented pre-conditionsAll data members privateEvery constructor initializes every data memberAppropriate treatment of default constructorAppropriate treatment of the Big 3Appropriate relational operatorsAppropriate output functionConst correctnessRedundant or generalizable functions
