c++ - volatile member can not be accessed by member function -


निम्न कोड मेरे प्रोग्राम को क्रैश करता है: 

  #include & lt; स्ट्रिंग & gt; #include & lt; vector & gt; क्लास टेस्ट {volatile std :: vector & lt; std :: string & gt; WTF; सार्वजनिक: परीक्षण () {} शून्य डोप () {wtf.clear (); }}; Int main () {(नया परीक्षण ()) - & gt; डोप (); वापसी 0; }

और मुझे पता नहीं क्यों है जब मैं अस्थिरता निकालता हूं, यह फिर से काम करता है। तो क्यों अस्थिर एक समस्या है?

std :: vector :: स्पष्ट () में अस्थिर योग्यता नहीं है।

इसलिए इसे अस्थिर वेक्टर के साथ बेकार करना अवैध है।

BTW, अस्थिर बहु-थ्रेडिंग के लिए एक जादू कीवर्ड नहीं है।
आप अपने वेक्टर तक पहुंच की रक्षा के लिए mutex का उपयोग कर सकते हैं।

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...

Is there any way, I can get some parameters from the header, cookies (log in userId in my case) , And then apply it in a form which I know who will deposit the ticket?

What is the call to apply the request, when I can use it (and also a good practice?) Edit An issue, absolutely deceiving anyone if I were to create a hidden area with this value. It could Ript, but the issue may be re-used in any way to verify and return the form, it can not be sure how it ....
