所以,我正在用线程做一些基准测试,我写了这些代码:

resp_threadless []和resp_threaded []是全局int数组,它们的大小是n;

int n = 100000;

void function() {
  for (long j = 0; j < n; ++j) {
    int count = 0;
    double x = vetor[j];
      while (x > 1.0) {
      x = sqrt(x);
      ++count;
    }
   resp_threadless[j] = count;
  }
}

DWORD WINAPI function_th( LPVOID lpParam ) {
for (long j = 0; j < n; ++j) {
    int count = 0;
    double x = vetor[j];
      while (x > 1.0) {
      x = sqrt(x);
      ++count;
    }
   resp_threadless[j] …
