只能说相见恨晚
当我运行下面的代码时,程序无法得到任何输出,似乎是卡在了某个地方,请问是哪里出错了呢。
源出处
#include <iostream>
#include <thread>
#include <atomic>
#include <list>
#include <iostream>
using namespace std;
class Solution {
public:
Solution()
: state_{State::READ},
trd_{[this]{
this->customer();
}
}
{ }
void producer(int val)
{
while(state_.load(std::memory_order_acquire) == State::READ);
task_.push_back(val);
state_.store(State::WRITE, std::memory_order_release);
}
void customer()

while(state_.load(std::memory_order_acquire) == State::WRITE);
if(!task_.empty()) {
int val = task_.front();
cout<<val<<endl;
task_.pop_front();
