Fill in the blanks to build the Triangle Class, and then to fill in the (main) program below. Select the appropriate information from the list of options provided. Take into consideration that the class that is developed meets the following description:

1) The class is called Triangle and it has 3 attributes called a, b, c. These represent the length of the 3 sides of a triangle.

2) The functions of the class (methods) are (the code must comply with these descriptions): Function A) Constructor function, which receives 3 parameters that are the initial values to be stored in an object of type Triangle when the object is created. The constructor is expected to have defaults of 1.0 defined for the parameters (default parameters).

Function B) Set function, which receives as parameters the new values to be stored in an object of type Triangle. This function verifies that the values received to store in the data members are positive, and if they are not, it stores a default of 1.0 in the corresponding data member.

Function C) Perimeter function, which calculates and returns the perimeter of a triangle (remember that the perimeter is the sum of the lengths of the 3 sides of the triangle).

Function D) Area function, which calculates and returns the area of a triangle. The formula to calculate the area of a triangle when the length of the 3 sides is known is the following (it is already written in C ++):

s = (a + b + c) / 2.0;

Ar = sqrt(s * (s-a) * (s-b) * (s-c))

Function E) Print function, which prints the sides of the triangle with the following format (assuming that the lengths of the three sides are, for the purposes of this example, 1.5, 3.3, 2.1):

Side 1: 1.5

Side 2: 3.3

Side 3: 2.1
