Extracted text: A Parallelogram is a flat shape with opposite sides parallel and equal in length. The diagonal of a parallelogram divides it into two congruent triangles. So the total area of the Parallelogram is always twice the area of one of the triangles formed by the diagonal as below A = Vab sin (c) where, "a" and "b" are the two sides and "c" is the angle in radian. Write a C++ program that computes the area A of Parallelogram by reading its parameters from a text file "input.txt". Each line of the file represents the parallelogram name, the side "a", side "b" and the angle "c" of a Parallelogram, respectively. The program should read each line to compute the area A of each parallelogram. It should also display the total number of computed areas. Your program should implement the following functions: Area(): This function receives the values of "a", "b", and "c" then computes and returns the value of area A. Print(): This function receives the name of Parallelogram and the computed area A then displays on the output screen.
