c ++中类似Java的Arrays.asList（）

Question

Does c++ support either in the STL or there exists an external library supporting Arrays.asList() ?

Typical usage

private ArrayList<String> lexeme = new ArrayList<String>(Arrays.asList(" ", ",", "(", ")", ";", "=", ".", "*", "-"));

I am using Visual Studio 11 (2012) and they have not included the c++11 feature Initializer lists leaving me in a quandry as to initialize a vector of nine unique strings without

std::vector<std::string>::push_back("a");
std::vector<std::string>::push_back("b");
std::vector<std::string>::push_back("c");
                 . . .

Answer 1

A common thing to do before C++11 was to first create an array, then initialize the vector with it, for example:

char const * arr[] = { " ", ",", "(", ")", ";", "=", ".", "*", "-" };
std::vector<std::string> str_vec(arr, arr + sizeof(arr) / sizeof(*arr));

Of course, VS11 does support some of C++11, so you can do this instead, which is slightly more readable:

char const * arr[] = { " ", ",", "(", ")", ";", "=", ".", "*", "-" };
std::vector<std::string> str_vec(std::begin(arr), std::end(arr));

Answer 2

You could use:

const char* arr[] = {"a", "bc", "def"};
std::vector<std::string> vec(std::begin(arr), std::end(arr));

If your compiler doesn't support std::begin() and std::end() , they are easy to do without:

std::vector<std::string> vec(arr, arr + sizeof(arr) / sizeof(*arr));
