You can do it the right way?

If you take the second for becomes as?

Now I understood I took a for and put the variable i out of it..

for(int i=0; i<6;i++) { Std::Cout.Imbue(Std::locale(lang_utf[i]); Std::Cout << lang[i] << Std::put_time(Std::gmtime(&time), "%c") << " n"; } .

You don’t need two ties to solve the problem, only one is enough:

#include <iomanip>
#include <iostream>

int main(void)
{
    std::time_t now = std::time(nullptr);

    std::string lang[6] = { "pt_BR", "en_US", "en_GB", "de_DE", "ja_JP", "ru_RU" };

    for( int i = 0; i < 6; i++ )
    {
        std::string loc = lang[i] + ".utf8";

        try
        {
            std::cout.imbue(std::locale(loc));
            std::cout << lang[i] << ": " << std::put_time(std::gmtime(&now), "%c") << std::endl;
        }
        catch( std::exception &e )
        {
            std::cout << lang[i] << " nao suportada!" << std::endl;
        }
    }

    return 0;
}

Compiling code in default C++11 using the compiler GCC v5:

g++ -std=c++11 main.cpp -o teste

Exit:

pt_BR nao suportada!
