How correctly convert int to std::string?

#include <SFML/Graphics.hpp>

using namespace sf;
using namespace std;

int main()
{
    sf::RenderWindow window(sf::VideoMode(400, 200), "SFML text test");
            sf::Font font;
            sf::Text Ttext;
                 int Pscore;
         std::string score, score2;

    std::srand(static_cast<unsigned int>(std::time(NULL)));

    if (!font.loadFromFile("sansation.ttf"))
        return EXIT_FAILURE;

    Ttext.setFont(font);
    Ttext.setCharacterSize(30);
    Ttext.setPosition(50.f, 20.f);
    Ttext.setColor(sf::Color::Black);
    Pscore = std::rand() % 6;
    score2 = "\nTotal";
    score = "Score " + Pscore + score2;
    Ttext.setString(score);


    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }

        window.clear(sf::Color::White);
        window.draw(Ttext);
        window.display();
    }

    return 0;
}

If I recall correctly you don't have std::to_string() on mingw you need to find a workaround

Ever heard of search engines?
What do int and std::string have to do with the Graphics module of SFML?

[Hapax]

uses namespaces

using namespace sf;
using namespace std;

then...

sf::RenderWindow window(sf::VideoMode(400, 200), "SFML text test");

sf::Font font;

sf::Text Ttext;

std::string score, score2;

std::srand(static_cast<unsigned int>(std::time(NULL)));

Ttext.setColor(sf::Color::Black);

Pscore = std::rand() % 6;

sf::Event event;

Best suggestion is to remove the "using namespace" lines. It'll still work fine since you're correctly fully qualifying everything already.

Thanks Strelok! Working.

How about add to SFML this function:

#include <sstream>

std::string Convert_Int_to_str(int Integer)
{

std::string result;

result = static_cast<std::ostringstream*>( &(std::ostringstream() << Integer) )->str();
return result;

}

This will useful function for some guys like me.

There's no reason to have something like that in SFML.

1. It's trivial to implement yourself (using sprintf, string stream, boost::lexical_cast & more).
2. Modern C++11 has std::to_string.
