c++ - Using a free "char const*" at static initialization time -


The initial order of free objects is undefined in C ++ but what about the following? 

  named place foo {char const * str = "hey"; Structure A {A () {cout & lt; & Lt; Str; }} Obj; }

Is it still an undetermined behavior, or is there a special provision for pointers started with string literals?

Apart from this : What if str was a type "four const []"? And if it was a std :: string

Even if they were located in different translation units, the initial order Is still defined

That's because str is started with a constant expression ( address continuous expression ) and str has pod-type, it will still be correct if you have an array but if you had a std :: string , then it would not be true now those dynamically started New have (because std :: string is a non-POD).

Thus, if your str was a std :: string , then if you define obj then you are undefined In practice, a separate translation unit will run, but for the list you are listed on, this will be the only issue that will cause trouble.

I have been trying to use Qt5 multimedia to record audio with QAudioInput, however, when I see If QAudioInput is started, it increases the master volume of my sound device to 100%.
