Write a program to find the area of a triangle , follow these steps:

Accept the sides of a triangle in the main.

Build a function to accept the sides of the triangle (check if the sides form a triangle if yes returns the area otherwise returns zero.

Call the function from the main then print the area of the triangle in the main if the sides form a triangle, if not print sides dont form a triangle.

Let the program find the area for three triangles.

Hint: use this formula to find the triangle area:

Area=

Hint: use this formula to find the triangle area: Area-Vs(s-a) (s-b) (s-c)
