Threads
To use the multithreading interface of C++ you need the header <thread>.
Creation
A thread std::thread represents an executable unit. This executable unit, which the thread immediately starts, gets its work package as a callable unit. A callable unit can be a function, a function object or a lambda function:
// threadCreate.cpp
...
#include <thread>...
using namespace std;
void helloFunction(){
cout << "function" << endl;
}
class HelloFunctionObject {

thread t3([]{ cout << "lambda function"; }); // lambda function
Lifetime
The creator of a thread has to take care of the lifetime of its created thread. The executable unit of...
