Problem Statement
-----------------

        1) For the program given below
                a) Identify if loop can be vectorized.
                b) Identify if loop can be parallelized.
                c) Verify your claim using gcc-4.7.2.

        2) Loop  transformations  generally  enable other  optimizations.  Apply
           suitable loop transformation and write an equivalent c code for which
           gcc-4.7.2 will completely  parallelize/vectorize loops in transformed
           program. Also verify this using gcc-4.7.2.

        int main ()
        {
                int i,n;
                int A[500],B[500],C[500];
                for (i=1; i<500; i++) 
                {
                        A[i] = C[i] + A[i-1];   /* S1 */
                        C[i-1] = A [i-1] + B[i] + 10; /* S2 */
                }
                return (A[n]+C[n]);
        }
