- 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 constructors, one that takes String, int, int that represents 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…arrow_forwardThe push member function simulates the push of a numeric button with value 0 to 9. The open member function simulates the push of the # key that causes the lock to open, provided that the right combination was entered. (For now, the combination is hardwired as 1729. You will see in Section 9.6 how to change it.) As the data representation, use an integer containing the digits that have been entered up to this point. You will need to figure out how to update that number. For example, if the user had previously pushed 1 and 7, causing input to be 17, and now pushes 9, how can you set input to 179? In the open member function, return true if the lock would have been opened, false otherwise. Clicking that button resets the entered keys, whether or not the correct combination has been entered. Complete the following file: c++ please #include <iostream>using namespace std; /**A simulated lock with digit buttons.*/class Lock{public:/**Simulates a digit button push.@param button a digit…arrow_forwardIn C++ implement the relational operators (<, <=, ==, !=, >, >=) in the Circle class in the code below, to order the Circle objects according to their radii.
