C++11: Stack vs Queue Thread Safety

What are the differences in thread safety between std::stack and std::queue in C++11?

In C++11, both std::stack and std::queue are not inherently thread-safe. You need to implement your own synchronization.

Can you explain how I can make them thread-safe?

You can use mutexes to lock access to the stack or queue when multiple threads are involved. This ensures that only one thread can modify the data structure at a time.

Are there any specific examples of using mutexes with std::stack?

Sure! You can use std::mutex along with std::lock_guard to manage access. For example:

std::stack<int> myStack;
std::mutex stackMutex;

void pushToStack(int value) {
    std::lock_guard<std::mutex> lock(stackMutex);
    myStack.push(value);
}

What about using condition variables with these data structures?

Condition variables can be used to manage waiting and notifying between threads. For instance, you can wait for the stack to have elements before popping.
