Consider the following code and its output:
#include
#include
#include
using namespace std;
void f(const string& s) {
for (auto n: { 1,2,3})
cout << s << endl;
}
int main() {
auto tl = thread{f, "Go ahead"};
auto ti = thread{f, "make my day"};
t1.join();
t2. join());
}
/* Output:
mGaok ea hmeya dday
Gmoa kaeh emayd
daGyo
amhaekaed
my day
*/
Insert code in the program above so that the output is not jumbled, but each line is separate. It must be exception-safe. (Note: do not change any code, but only add lines. Characters must continue to be output one at a time.)
