Как сделать многозадачность в С++ ( простейшее )

WINAPI:

#include
#include

DWORD WINAPI tf1(void {
int n = 10;
while (n--) std::cout << "thread #1\n";
return 0;
}

DWORD WINAPI tf2(void {
int n = 10;
while (n--) std::cout << "thread #2\n";
return 0;
}

int main() {
HANDLE t1, t2;

t1 = CreateThread(0, 0, tf1, 0, 0, 0);
t2 = CreateThread(0, 0, tf2, 0, 0, 0);

WaitForMultipleObjects(2, &t1, TRUE, INFINITE);

return 0;
}

PTHREADS:

#include
#include

void *tf1(void {
int n = 10;
while (n--) std::cout << "thread #1\n";
return 0;
}

void *tf2(void {
int n = 10;
while (n--) std::cout << "thread #2\n";
return 0;
}

int main() {
pthread_t t1, t2;

pthread_create(&t1, 0, tf1, 0);
pthread_create(&t2, 0, tf2, 0);

pthread_join(t1, 0);
pthread_join(t2, 0);

return 0;
}

C++11:

#include
#include

void tf1() {
int n = 10;
while (n--) std::cout << "thread #1" << std::endl;
}

void tf2() {
int n = 10;
while (n--) std::cout << "thread #2" << std::endl;
}

int main() {
std::thread t1(tf1);
std::thread t2(tf2);

t1.join();
t2.join();

return 0;
}
