Part 2: One hour, Program writing Marks : 40 a) Consider the following series, this series will evaluate the value of Y(x) from n = 0 up to Infinity, for any value of x greater than 2. Y(x) = (-1)" for x > 2.0 Y(st) = 0.0 for xs 2.0 Using function, develop a C++ program that will ask the user to enter the value of x and will return Y(X). The program will keep running until - 13" is less than +1.2 x 10-9 Please enter the value of x: ** The value of Y(x)= Mack 1 1 1 1 Marking scheme Part Documentation Compiler directives Comments Ilona Output Variable Declaration Fermine Function prototype Functions Return value Total 2 2 2 5 2 20
