Need a C++ program. provide the output as well thank you.

2. Let a, b, c be the lengths of the sides of a triangle. The area is given by where p is half the perimeter, or (a+b+c)/2 Define two value returning functions The first one named is Triangle that takes three sides of the triangle and return the true if they can make a triangle. It returns false if they cannot make a triangle. (The sum of the lengths of any two sides of a triangle is greater than the length of the third side.) The second function named TriangleArea, that takes three edges of the triangle and calculates the area of the triangle. The function needs to validate the lengths of three sides to ensure they can make a triangle before it computes the area. In the main), ask the user to input three sides and output the area. Make some runs that can test triangles and non-triangles.
