Hi all,
In the code below, an assignment operator is used on the second line in main function.
I am curious to see how the initializer_list assignment operator looks like but I can't find its code in the STL library.
The class definition in /usr/include/c++/5/initializer_list does not provide any assignment operator.
Could anyone please tell me in which file it is defined ?
Thank you in advance
// initializer_list example
#include <iostream> // std::cout
#include <initializer_list> // std::initializer_list
int main ()
{
std::initializer_list<int> mylist;
mylist = { 10, 20, 30 }; ///<---------- ???????
std::cout << "mylist contains:";
for (int x: mylist) std::cout << ' ' << x;
std::cout << '\n';
return 0;
}

As legacy from C the C++ compiler makes assignment operators implicitly

for structs/classes when it is not explicitly done by user.
Besides that 'std::initializer_list' is a "magical" class and so not all
of its behavior is possible to implement as library code.
