Threading Library
Basics
- What is multithreading?
- Why multithreading?
Overview of C+ thread library
Let us start with an easy example:
#include <iostream>
#include <thread>
void helloFunction() {
std::this_thread::sleep_for(std::chrono::milliseconds(rand() % 1000));
std::cout << "Hello from a thread!\n";
}
int main() {
std::thread t1(helloFunction);
std::thread t2(helloFunction);
std::cout << "We have launched two threads to operate in parallel!" << std::endl;
t1.join(); // Wait for the thread to finish
t2.join();
return 0;
}
