C++ array initialization

Question

Why can’t I initialize a local array with a string

Answer 1

Why can’t I initialize a local array with a string

The correct answer is that you can – for a given definition of array, and string. What exactly do you want to achieve?

char str[] = "Hello world";

Answer 2

The question is very skinny on details but:

char arr[] = {'a','b','c', 0};

or

char arr[] = "string";

EDIT:

In response to questions:

char s1[] = "hi";
char s2[] = {'h','i',0};
memcpy(s1, "by", sizeof(s1));
memcpy(s2, "by", sizeof(s2));
cout << ios::hex << &s1 << endl;
cout << ios::hex << &s2 << endl;
cout << s1 << endl;
cout << s2 << endl;

Prints:

80xbfffed72
80xbfffed6f
by
by

At least on my system it looks like both are allocated in the same memory space, I don't see any problems or differences. C for example defines string as a null terminated char array - I believe this is the same in C++, not to be confused with std::string.

Answer 3

std::vector<std::string> abc(5,"abc");

will create a vector with 5 elements initialized to "abc".
