2-Topshiriq.

Quyidagicha dastur tuzing.

Dastur shartlari:
Dastur sizdan ismingizni, familiyangizni va tug’ilgan kuningizni kiritishni so’rasin.
Agarda siz toq sanada tug’ilgan bo’lsangiz ism familiyangizni 1 marta ekaranga chiqailsin aks holda n marta (n ta oqim orqali) chiqarilsin(n-tug’ilgan kuningiz sanasi).

#include

#include
using namespace std;
int main()
{
int n=0;
cout<<"To'g'ilgan kuningizni kiriting: ";
cin>>n;
#pragma omp parallel if(n%2==0)num_threads(n)
{
cout<<"Qobulov Asror thread num-"<< omp_get_thread_num()<}
}



3-Topshiriq.
n ta oqim uchun ichki parallellikni yoqing va ichki parallellik yonganligini isbotlang.(n jurnaldagi tartib raqamingiz)
