The below program use the for loop to calculate the sum up to n numbers. Convert this program to OpenMP API code using the appropriate constructor. Decide whether you need to apply critical section in this code and explain your justification.

#include

int main() {

int n, i, sum = 0;

printf("Enter a positive integer: ");

scanf("%d", &n);

for (i = 1; i <= n; ++i) {

sum += i; }

printf("Sum = %d", sum);

return 0;
