我正在学习编写多线程应用程序.因此,即使使用互斥锁,我也希望我的线程能够访问简单的共享资源.
例如,考虑以下代码:
using namespace std;
mutex mu;
std::vector<string> ob;
void addSomeAValues(){
mu.lock();
for(int a=0; a<10; a++){
ob.push_back("A" + std::to_string(a));
usleep(300);
}
mu.unlock();
}
void addSomeBValues(){
mu.lock();
for(int b=0; b<10; b++){
ob.push_back("B" + std::to_string(b));
usleep(300);
}
mu.unlock();
}
int main() {
std::chrono::steady_clock::time_point start = std::chrono::steady_clock::now();
thread t0(addSomeAValues);
thread t1(addSomeBValues);
std::chrono::steady_clock::time_point end = std::chrono::steady_clock::now();
t0.join();
t1.join();
//Display the results
cout << "Code Run Complete; results: \n";
for(auto k : ob){
cout << k <<endl;
}
//Code running complete, report the time it …Run Code Online (Sandbox Code Playgroud)
