Change string locale

I'm not very familiar with locale-specific conversions so I may be using th开发者_StackOverflow中文版e wrong terminology here. This is what I want to have happen.

I want to write a function

std::string changeLocale( const std::string& str, const std::locale& loc )

such that if I call this function as follows:

changeLocale( std::string( "1.01" ), std::locale( "french_france" ) )

the output string will be "1,01"

Thanks for your help!

Something like this ought to do the trick

#include <iostream>
#include <sstream>
#include <locale>
int main (int argc,char** argv) {
    std::stringstream ss;
    ss.imbue(std::locale("fr_FR.UTF8"));
    double value = 1.01; 
    ss << value; 
    std::cout << ss.str() << std::endl; 
    return 0;
}             

Should give you output of 1,01 (at least it does on g++). You might have to fiddle with the locale specification since it's very specific to platform.
