How can I get the full text at SDL? (Not console) - c++

Question

I am creating a menu for a game at C++ and I have a problem when I read a text file (.cfg), and I want to show it to the screen (With SDL,not console).
The problem is that in SDL, I only get the last line. Why is that?
Here is my code:
fstream characters;
characters.open("characters.cfg", ios::in);
while (getline(characters, line))
cout << line << endl;
And I create a string to show it with SDL_ttf:
void renderUI() {
SDL_Surface* textSurface;
SDL_Texture* textTexture;
SDL_Rect textRect;
SDL_Color white = { 255,255,255 };
textRect.w = 250;
textRect.h = 20;
textRect.x = 150;
textRect.y = 200;
string names = line;
textSurface = TTF_RenderText_Blended(gameFont, names.c_str(), white);
textTexture = SDL_CreateTextureFromSurface(renderer, textSurface);
if (textSurface == NULL)
{
cout << "TTF_RenderText_Solid() Failed: " << TTF_GetError() << endl;
TTF_Quit();
SDL_Quit();
exit(1);
}
SDL_RenderCopy(renderer, textTexture, NULL, &textRect);
}
And here a photo to show that I get the full text in the console, but not in SDL:

I have the solution. Here is the code:
fstream characters;
string line;
string text;
characters.open("characters.cfg", ios::in);
while (getline(characters, line))
{
text = text + line + "\n";
}
characters.close();
And here´s the code of SDL_ttf and the solution to the line break problem with SDL:
SDL_Surface* textSurface;
SDL_Texture* textTexture;
SDL_Rect textRect;
SDL_Color white = { 255,255,255 };
textRect.w = 250;
textRect.h = 400;
textRect.x = 150;
textRect.y = 185;
textSurface = TTF_RenderText_Blended_Wrapped(gameFont, text.c_str(), white, 500);
textTexture = SDL_CreateTextureFromSurface(renderer, textSurface);
// If TTF_RenderText_Solid() Fail
if (textSurface == NULL)
{
cout << "TTF_RenderText_Solid() Failed: " << TTF_GetError() << endl;
TTF_Quit();
SDL_Quit();
exit(1);
}
Used this for the line break problem with SDL_TTF:
TTF_RenderText_Blended_Wrapped for be able to use line break
