如何构建 std::vector<std::string> 来自 std::initializer_list<char const*>

Question

What is the correct way to build an std::vector<std::string> from an std::initializer_list<char const*> ? I can iterate through the initializer list and manually build up the vector as such:

std::initializer_list<char const*> values;
std::vector<std::string> vec;
for(auto v : values) {
    vec.push_back(v);
}

Seems quite verbose. Suggestions?

std::vector有一个接受迭代器范围作为输入的构造函数，只要解引用的值可以转换为向量的value_type ：

std::vector<std::string> vec(values.begin(), values.end());
