for initiailzer_list , why does Cpp provide only the default constructor: cppreference ;
then let me initialize vector:
struct A{
A(int a, int b){this->a = 2*a; this->b = 2*b;}
int a;
int b;
};
A a{1, 2}; // (2, 4)what is brace (list) initialization designed for?
which compiler does the main building use? Vector < int > vec (initializer_list < int > ()); gPP7.3 can be compiled in the past
parenthesis initialization is ambiguous, and calling the constructor is indistinguishable from the function declaration. That's why CPP11 added curly braces for initialization.
