Question 1: The BoxType class holds the length, width, and height of a box. Instances of the BoxType class are considered equal if their respective volumes are equal. Arithmetic can be performed on instances of the BoxType class by performing arithmetic operations on their respective dimensions. Consider that box1s length = 4, width = 5, and height = 9. Consider that box2s length = 3, width = 2, and height = 3. BoxType box3 = box1 box2; box3 will have a length of 1 and a width of 3 and a height of 6. BoxType objects can be incremented/decremented by increasing/decreasing their respective dimensions by 1. Consider that box1s length = 4, width = 5, and height = 9. box1++; box1 now has a length of 5 and a width of 6 and a height of 10. Write the BoxType class and overload the following operators (using either member or nonmember functions): Addition, Subtraction, Multiplication, Division, Greater Than, Less Than, Equal To, Not Equal To, Pre-Increment, Pre-Decrement, Post-Increment, and Post-Decrement. Keep in mind that a box cannot have negative dimensions. If any calculation results in a negative dimension, set all dimensions to the default 0. Next, overload the stream insertion and stream extraction operators, so the following main test function produces the shown output. Your BoxType class and operator overloads should work with the included main function. Please dont alter main.
