I'm trying to load numbers from a file. I've tried using getline() but that always says it cannot convert from char* to int. So I try the get() function and I get this

323 C:\My Documents\Jake's Documents\Dragons End\Helper.cpp no matching function for call to `std::basic_ifstream<char, std::char_traits<char> >::get(int&)'

What does it mean and what can I do.

And it's in a .txt file. Is that my problem?

Can you show us the function that is reading the file?

void LoadGame() {
	 
	ifstream File("C:/stats.txt");
	
	char name[32];
	char load[32];
	int amount;
	
	File.getline(name,32);
	player.SetName(name);

		File.get(amount);
		player.SetAttack(amount);
	
		//Load Everything

	File.close();
	
	cout << player.GetName() << endl;

		cout << player.GetAttack() << endl;

		//Display Everything
	
	Wait();
}

Here it is.

Its quite simple actually, if its a number all you need to do is

File >> amount

where amount is your integer you defined. and "File" is your ifstream variable, heres a sample function I made for you to look at, and if you want it to be an array then just add a for loop within to go through the different elements of the variable:
Input without For loop

int number;
  ifstream myfile ("example.txt");
  if (myfile.is_open())
  {
	while (! myfile.eof() )
	{
	  myfile >> number;
	}
	myfile.close();
  }

  else {
	  cout << "Unable to open file" << endl; 
  }

Example with for loop

int number[10];
  ifstream myfile ("example.txt");
  if (myfile.is_open())
  {
	while (! myfile.eof() )
	{
		for(int x = 0; x < 10; x++) {
			myfile >> number[x];
		}
	}
	myfile.close();
  }

  else {
	  cout << "Unable to open file" << endl; 
  }
