C++11 string initialization

Question

I need to create a string of 100 A characters.

Why does the following

std::string myString = {100, 'A'};

give different results than

std::string myString(100, 'A');

?

Answer 1

std::string myString = {100, 'A'};

is initialization using initializer list. It creates a string with 2 characters: one with code 100 and 'A'

std::string myString(100, 'A');

calls the following constructor:

string (size_t n, char c);

which creates a string with 100 'A's

Answer 2

The first initializes it to values of 100 and A and the second calls a constructor overload of std::string.
