- Problem Class In this exercise, you are going to create the Problem class. The Problem class is used to help simulate a math fact, for example: 2 + 5 = Your class needs to contain two contructors, one that takes String, int, int that represts the operator sign(+, -, *, or /), the minimum, and maximum values for the number range, and a second constructor that takes only a String that represents the operator sign. For the second constructor, the minimum should default to zero and the maximum to ten. Your Problem object should generate 2 random integers between the minimum and maximum values (inclusively). Each Problem object should only have one set of numbers that do not change. While you may include additional helper methods, two methods need to be available to the user. The first is the answer method that should return a double that represents the answer to the problem. The second is the toString that should return a String that represents the problem. The format should be: number…Create a calculator for the number by creating a class of number with overloading all operators in it.(Operators: ++,--,+,-,/,*, >>, <<)Rules: Corner cases. By convention, the row and column indices are integers between 0 and n − 1, where (0, 0) is the upper-left site. Throw an IllegalArgumentException if any argument to open(), isOpen(), or isFull() is outside its prescribed range. Throw an IllegalArgumentException in the constructor if n ≤ 0. Unit testing. Your main() method must call each public constructor and method directly and help verify that they work as prescribed (e.g., by printing results to standard output). Performance requirements. The constructor must take Θ(n^2) time; all instance methods must take Θ(1)Θ(1) time plus Θ(1)Θ(1) calls to union() and find().
- In C++ QUESTION 14 class rectangleType { public: void setLengthWidth(double x, double y); //Sets the length = x; width = y; void print() const; //Output length and width double area(); //Calculate and return the area of the rectangle (length*width) double perimeter(); //Calculate and return the perimeter (length of outside boundary of the rectangle) private: double length; double width; }; Write the function definition for the function perimeterInstructionsDefine an enumeration type triangleType that has the values scalene, isosceles, equilateral, and noTriangle.Write a function triangleShape that takes as parameters three numbers, each of which represents the length of a side of the triangle. The function should return the shape of the triangle. (Note: In a triangle, the sum of the lengths of any two sides is greater than the length of the third side.)Write a program that prompts the user to input the length of the sides of a triangle and outputs the shape of the triangle.Consider the following code segment and answer questions 14 and 15. class Point { public: Point (double x = -99, double y = -99) { this -> xM = x; this -> yM = y;} double getx () {return xM; } double gety () {return yM; } void setx (double x) {this -> xM = x; } void sety (double y) {this -> yM = y; } private: double xM, yM; }; 14. What is the output of the following code snippet: Point pl (100); cout << pl.getx() << " " << pl.gety(); a. The output of the program is: -99 -99 b. The output of the program is: 100 100 c. The output of the program is: -99 100 d. The output of the program is: 100 -99 e. None of the above. It doesn't compile because constructor of Point needs two arguments. 15. How many times does the constructor of class Point get called by the following code snippet: Point a (100, 200); Point b[6]; Point *c = new Point; Point *d = new Point (300, 400); a. Four times b. Three times c. Nine times d. Two times e. None of the above
