Question

I don’t understand why is it possible to do this:

int numbers[] = {-4,3,0,100,2000};
Set d(5,numbers);

but I get the following error when trying to do this:

Set d(5,{-4,3,0,100,2000});

Error:
warning: extended initializer lists only available with -std=c++0x
         or -std=gnu++0x|
error: no matching function for call to
         'Set::Set(int, <brace-enclosed initializer list>)'

Constructor:

Set::Set(int size, const int constSet[])

Thanks for your help

Answer 1

This is not allowed in C++03, but the newest standard C++11 allows it.

See this: https://en.wikipedia.org/wiki/C%2B%2B11#Initializer_lists or this: https://www2.research.att.com/~bs/C++0xFAQ.html#init-list

By the way, your constructor is actually taking a pointer, not an array.
