No Instance of overloaded function vector of structs - c++

Question

I creating a project from college where I have to recreate the Scrabble Junior game to a console Game, but I've got a problem and i question in my code.
Firstly, I've got an error in my code saying :
"no instance of overloaded function "std::vector<_Ty, _Alloc>::push_back [with _Ty=Board::Word, _Alloc=std::allocator<Board::Word>]" matches the argument list
argument types are: (Board::Word)
object type is: std::vector<Board::Word, std::allocator<Board::Word>>
The struct Word is this one:
struct Word {
int row;
int column;
char orientation;
int tilesadded = 0; //starts at 0
int wordlength;
bool completed = false;
int currentletterpositiontoAdd[2]; //array to hold the coordenates of the next tile to be added
std::string name;
};
This struct basically stores every word and it's position in the board
And then I have also a vector storing every word struct: std::vector <Word> words;
The code that builds this struct is the following (because I get from a file every word and position to the board):
void Board::GetBoard()
{
std::ifstream file;
std::string filename, input;
std::cout << "----------------------------------------------------------------------------------------" << std::endl << std::endl;
std::cout << "What is the directory of the board file? (.txt is added for you) -> ";
while (std::getline(std::cin, filename))
{
file.open(filename + ".txt");
if (!file.is_open())
{
std::cin.clear();
file.clear();
RED;
std::cerr << "Error reading file." << std::endl;
WHITE;
std::cout << "What is the directory of the board file? (.txt is added for you) -> ";
}
else
break;
}
while (std::getline(file, input))
{
if ((int)input[0] == 49 || (int)input[0] == 50)
{ //this means that its the first line of the file and the first character is either 1 or 2
boardSize = stoi(input.substr(0, 2));
}
else
{
std::string nametoCat;
Word word;
word.row = input[0] - 'A' + 1; //calculation of the position on the board using ascii code ex: input[0] = C so: 'C' -'A' + 1 = 3 row -> 3
word.column = input[1] - 'a' + 1; //calculation of the position on the board using ascii code ex: input[1] = e so: 'e' -'a' + 1 = 5 column -> 5
word.orientation = input[3];
word.currentletterpositiontoAdd[0] = word.row;
word.currentletterpositiontoAdd[1] = word.column;
for (int x = 5; x < 1000000000; x++)
{ //for loop to check the name ending and build a string with the name
if (input[x] == '\0')
break;
else
nametoCat += input[x];
}
word.name = nametoCat;
word.wordlength = word.name.size(); //storing the word length to use later to check if word is completed in board
words.push_back(word);
}
}
}
The file looks like this:
15 x 15
Ak H EGGS
Bg H BUZZ
Ca H MUSIC
Cm H ARM
...
And secondly, I would like to make the code look more "clean" and understandable and remove that 1000000000 from: for (int x = 5; x < 1000000000; x++) and do it another way, but i can't find a solution. Because this 1000000000 looks like a magic number and not a number that would always work, for example, wouldn't work with a word of size 1000000001 (unlikely but possible).
Thank you.
