Please help me...I'm a noob

Hi!
I've got a problem with this piece of C++ code.
//Calculate width
unsigned int Width = 0;
while( mRead.get() != '\n' )
{
Width++;
}
//Calculate height
unsigned int Height = 2;
while( !mRead.eof() )
{
if( mRead.get() == '\n' )
Height++;
} RIGHT UP 'TIL HERE IT WORKS JUST FINE
char* pLevel = new char[Width]; IS THIS POINTER CORRECT?
mRead.seekg( 0, ios_base::beg )
mRead.getline( pLevel , Width );
I WANT TO STORE THE DATA (TEXT), FROM THE FILE, IN THE CHAR ARRAY
FOR WHICH I ALLOCATED MEMORY WITH THE "NEW" COMMAND.
THEN I WANT TO DRAW IT ON THE SCREEN.
I KNOW THERE'S CODE MISSING AND SOME OF THE CODE I'VE WRITTEN IS PROBABLY ALL WRONG.
PLEASE HELP...WHAT'S MISSING? WHAT'S WRONG? ANY SUGGESTIONS?
GRATEFUL FOR ALL THE HELP I CAN GET.
Firstly, you can use the [sourse] and [/source] symbols on this forum so that you can write source like: (relace sourse with source)
Er, when you load the level into the char array you use getline. That will only load the first line of the level, won't it? You might want to do a loop for every row here, or just read width * height chars from the file.
Using eof is _IMHO_ a little messy. It's fine, but you could use an end-of-map delimiter character like ! or something, the way you use \n for the end-of-line delimiter. Your way is still perfectly ok though.
Do you know how to draw it on the screen? Are you planning to display it as text in a text-mode (like dos) display, or console, or do you want it to be displayed graphically?

Thank's for the replies!
I want to draw the level, in text format, in the console window (DOS).
Something like this:
000000000000000
000000000000000
000000000##0000
000000000##0000
0000##000000000
0000##000000000
000000000000000
000000000000000
And yes you're right my goal is to multiply Width with Height and draw the entire file...I just don't know how to do it.
If you possibly could give me a suggestion with a code sample or something, I would greatly appreciate it.
Thanks!

I haven't done text coding for years, and that was in pascal, but I think this method probably works fine.
drawing the level to the console
I'm not sure if clrscr is the right function.
This should write your map to screen. If you update the level and call drawLevel, the map will change on screen.
Now if your level looks like the one below, then 0's and #'s are going to be drawn on the screen. That's not really very pretty. The next step might be to store each square of map as a number and use an array to convert the number into a character, and possibly a color. I made a game doing this back in form four.
That would be something like:
replace printf("%c", pLevel...
with
I'm not sure if textcolor is the right function.
That should give you much more control of how your map looks without having to change the mapfiles.
Make sure you call the initialise before you try to load the level.

void drawLevel() { clrscr(); // Clear the text screen and reset the cursor to 0-0. for(int y = 0; y < Height; y++) { // Draw each row one at a time. for(int x = 0; x < Width; x++) { // Draw each character one at a time. printf("%c", pLevel[y * Width + x]; // Draw one charactr. } printf("\n"); }}I'm not sure if clrscr is the right function.

I used SetConsoleTextAttribute in a game I did and it worked pretty well, except I couldn't get a good color for orange. You need to include <windows.h> to use it.
