Array initialization

I have two types of array initialisation that will be used in string constructor

int main() {
 //char foo [] = { 'a', 'd' }; 
 char foo[] = "ad";
 std::string s = foo;
 cout<<s;
 int i;
 cin >> i;
}

Why in char foo [] = { 'a', 'd' }; case i have output:

ad╠╠╠╠╠╠R81ドル↑■しかく╬

And when array is initialized like char foo [] = "ad"; I have normal output -ad- that was expected in first case.

What is difference in these two array initialization and why I have garbage in output in first one?

  • "as compiler will generate a null terminate C string for you" Right, but explain why. Explain what difference in the code leads to this happening. Commented Oct 5, 2015 at 13:14
