Parallelization Issues

[Premas]

I tried to parallelize the below code using Par4all and I am able to get the parallelized code. But you can see that in the parallelized code, "n" is assigned with value 1410065407, instead of 1.0E10. Pls help me to solve the issue.

/** input code fragment **/

#define n 10000000000 for(i = 0 ; i < n ; i++) A[i] = i; for(i = 0 ; i < n ; i++) sum += A[i];

/Parallelized code/ #pragma omp parallel for for(i = 0; i <= 1410065407; i += 1) A[i] = i;

#pragma omp parallel for reduction(+:sum) for(i = 0; i <= 1410065407; i += 1) sum += A[i];
