thread in class c++ code example

Example 1: thread c++

// thread example
#include <iostream>       // std::cout
#include <thread>         // std::thread
 
void foo() 
{
  // do stuff...
}

void bar(int x)
{
  // do stuff...
}

int main() 
{
  std::thread first (foo);     // spawn new thread that calls foo()
  std::thread second (bar,0);  // spawn new thread that calls bar(0)

  std::cout << "main, foo and bar now execute concurrently...\n";

  // synchronize threads:
  first.join();                // pauses until first finishes
  second.join();               // pauses until second finishes

  std::cout << "foo and bar completed.\n";

  return 0;
}

Example 2: c++ create threads

#include <thread>
void foo() 
{
  // do stuff...
}
int main() 
{
  std::thread first (foo);
  first.join();
}

Example 3: c++ thread incide class

#include <iostream>
#include <thread>

class foo
{
public:
    void make_foo_func_thread()
    {
        t=std::thread(&foo::foo_func, this);
        t.join();
    }

private:
    std::thread t;
    void foo_func() { std::cout << "Hello\n"; }
};

int main()
{
    foo f;
    f.make_foo_func_thread();
}
