Loading a game map from a file and having the player move around

[MrMuffin]

Hey guys! I have this issue I need solved. I have looked on every website I possibly could've and haven't found anything, so I came to this forum.

How can I have a player move around on an ASCII map that has been loaded into the game from a text file? I want the player to move with the WASD keys. The player I don't care about collision right now, I can probably code that on my own if I know how to do movement by itself. The player should be the '@'.

Here is what the map looks like from the text file. It is 69x21 tiles in case that helps.

You need to set a x and y coordinate for the player. When the right key is pressed and x < the right border inc x. Similarly for all other movements.
After each movement you have to draw the map again.

Should I use vectors or a 2d array? If vectors, how would I call a specific element?

[Thomas1965]

You can use a 2d array since the number of columns and rows is fixed - at least I assume so.
I am not sure if you know OOP already, but I would do it like this - just an incomplete idea -

class Board
{
public:
  int GetRowCount ();
  int GetColCount ();
  char GetElem (const int row, const int col);
  void SetElem (const int row, const int col, const char elem);
  void Load (const char *filename);
  void Display ();
private:
  enum { ROWS = 21, COLS = 21 };
  char m_Fields[ROWS][COLS];
};


class Player
{ 
public:
  Player(Board board);
  void MoveRight ();
  void MoveUp ();
  void MoveLeft ();
  void MoveDown ();
  int GetCol ();
  int GetRow ();
private:
  Board m_Board;
  int m_Col, m_Row;
};

How would I load the map from a file and store it into the 2d array?
