request for member ‘c_str’ in ‘str’, which is of non-class

Question

main.cpp:561:80: error: request for member ‘c_str’ in ‘str’, which is of non-class type ‘std::string [10] {aka std::basic_string<char> [10]}’
   displayFont.showHighscore[i] = TTF_RenderText_Solid(displayFont.menuFont,str.c_str(), displayFont.colorText);

Hi all!

According this function, this shows a ranking with data that is retrived from a member class. Also this used ttf content from another class (displayFont). When I compile this, said an error. I leave the code:

void showHighscore() {

    displayFont.menuFont = TTF_OpenFont("fonts/Lanehum.ttf",25);
    displayFont.colorText = { 255, 255, 255 }; // Add content

    stringstream texting[10]; // Variables
    string str[10];
    SDL_Rect posHighscore[10];

    for (int i = 0; i < 10; i++) {
        texting[i] << i << "#    - " << dat.topScore[i];
        str[i] = texting[i].str();
        displayFont.showHighscore[i] = TTF_RenderText_Solid(displayFont.menuFont,str.c_str(), displayFont.colorText); // OUTPUTTING ERROR :/
        posHighscore[i].x = 50; 
        posHighscore[i].y = 50 * (i+1);
    }

    while (true) {
        for (int i = 0; i < 10 ; i++) {
            SDL_BlitSurface(displayFont.showHighscore[i],NULL,screen,&posHighscore[i]);     
        } // Show the rendered text

        SDL_Flip(screen);
        SDL_Delay(5000);
        break;
    }
}

Solution

str is an array of string:

 string str[10];

so you can't call str.c_str(). You need to call it on one of the elements of str, i.g. with an index:

str[i].c_str()
