none of above. program default have single thread of execution , execute each iteration of loop in series, without creating new ones.

only feature openmp (or similar) spawn different threads per iteration.

#include <omp.h>  #pragma omp parallel for(int n=0; n<10; ++n) { printf(" %d", n); } printf(".\n");
