Example
In below example for std::thread.
#include <iostream>
#include <thread>
void foo() {
std::cout << " foo is executing concurrently...n";
}
void bar(int x) {
std::cout << " bar is executing concurrently...n";
}
int main() {
std::thread first (foo);
std::thread second (bar,0);
std::cout << "main, foo and bar now execute concurrently...n";
first.join();
second.join();
std::cout << "foo and bar completed.n";
return 0;
}
The output should be like this −
main, foo and bar now execute concurrently... bar is executing concurrently... foo is executing concurrently... foo and bar completed.
