Complete Intermediate Exercise #$17$ at the end of the chapter.

Enter the class definition in a header file named Intermediate$17$ Triangle.h$.$ The class should include a void method that allows the program to set the triangle$$s dimensions. The method should verify that all of the dimensions are greater than $0\mathrm{.}0$ before assigning the values to the private data members. The class also should include two value$-$returning methods. One value$-$returning method should calculate the area of a triangle, and the other should calculate the perimeter of a triangle. The formula for calculating the area of a triangle is $1/2*$ b $*$ h$,$ where b is the base and h is the height. The formula for calculating the perimeter of a triangle is a $+$ b $+$ c$,$ where a$,$ b$,$ and c are the lengths of the sides. Determine the appropriate variables to include in the class. Be sure to include a default constructor that initializes the variables.

Submit only your Triangle.h File. Do not implement in a separate file. All definitions should be in Triangle.h$.$

DO NOT MODIFY THE chptr$15$main.cpp file. DO NOT CHANGE THE CLASS DECLARATIONS of Triangle.h$.$

Only modify the Triangle.h File by adding function implementations.

You can test your implementation of Triangle.h by running chptr$15$main.cpp$.$ Do not modify the chptr$15$main.cpp file, as you will be tested against the one attached to this assignment.
