The question is how to convert wstring to string?

I have next example :

#include 

int main()
{
    std::wstr         


        

Answer 1

Instead of including locale and all that fancy stuff, if you know for FACT your string is convertible just do this:

#include 
#include 

using namespace std;

int main()
{
  wstring w(L"bla");
  string result;
  for(char x : w)
    result += x;

  cout << result << '\n';
}
