我试图使用以下代码在C程序中获得并行效果：
#include<iostream>
using namespace std;
int main()
{
#pragma omp parallel sections
{
#pragma omp section
{
cout<<"Hello";
cout<<" ";
cout<<"World";
cout<<endl;
}
#pragma omp section
{
cout<<"H";
cout<<"ello";
cout<<" W";
cout<<"orld";
cout<<endl;
}
#pragma omp section
cout<<"Hello"<<" "<<"World"<<endl;
#pragma omp section
{ cout<<"Hello ";
cout<<"World"<<endl;
}
}
return 0;
}
我曾多次运行这个程序.由于并行性,我期待交错输出.
但是,每次运行此程序时,输出为：
Hello World Hello World Hello World Hello World
难道我做错了什么？
谢谢
