std::map initializer list syntax ?

C++11 supports the initialization of most containers by the simple syntax as follows:

Code:

---

std::set<int> = {3,4,6,34,2,6,78,8,5,0};
std::list<int> = {7,3,5,6,3,4,6,8};

---

Is there something equivalent to this for std::map `s which can be put outside all function code as the definition of the map ?

Yes, map also has a constructor that takes std::initializer_list<value_type>:

Code:

---

#include <map>
#include <string>
#include <iostream>

int main()
{
    std::map<int, std::string> m{{1, "Hello"}, {2, "world"}, {4, "!!!"}};
    for (std::map<int, std::string>::const_iterator it = m.begin(); it != m.end(); ++it) {
        std::cout << it->first << ' ' << it->second << '\n';
    }
}
