get the "space" when reading a file

[nickyeng]

i read a file, and the file contains this:

+-------------------+
|                     |
+-------------------+
 

when i read it into array, and then display it out to cout exactly the same as display in text file, but i failed to do so. it give me this :

+++++++++++++++++++++++
+++++++++++++++++++++++
+++++++++++++++++++++++
 

here is my code(it is the constructor ):

Terrain(char* filename =" " ): width(25) , height(11), ter_array(width, height){
 
                ifstream in(filename);
                if(!in){
                    cout << "Cannot open terrain file." << endl;
                }
 
                while(in >> piece){
                    for(unsigned y = 0; y < height; y++){
                        for(unsigned x = 0; x < width; x++){
                            ter_array.Put(x,y,piece);
                        }
                    }
                }
                in.close();
            };                // should i put ; in the end of this constructor?
 

note the comment line.

any one help...pls
I want the space inside the text file, store in array, so that it display the exactly the same to cout as in text file.

thanks in advance.

The nested loops concern me, especially the while....

The exact logic I'm not sure of, but I think basically, you always populate your array with all of 1 character...This means the array is full of (copies) of the current character at any time. because + is your last character, thi is what fills the array after you have read from the file.

Since you know the height & width, you could instead do something like:

Terrain(char* filename =" " ): width(25) , height(11), ter_array(width, height){
 
                ifstream in(filename);
                if(!in){
                    cout << "Cannot open terrain file." << endl;
                }
 
 
                    for(unsigned y = 0; y < height; y++){
                        for(unsigned x = 0; x < width; x++){
                                                                in>>piece;
                            ter_array.Put(x,y,piece);
                        }
                    }
 
                in.close();
            };                // should i put ; in the end of this constructor?
 

As far as I know too many semi-colons are never a problem, so even if you don't need the last one, there is little harm in including it

thanks but still, it cannot "get" whitespace between the characters.
the original text file:

+-----------------------+
 |                         |
 |           +-+--+ +-+
 |               |         |
 | +----+ +-------+    |
 | |      |                 |
 | |  +---+     +        |
 | |               |        |
 | +-----+  +--+ +    |
 |                   |     |
+------------------+----+
 

the whitespace inside the terrain, i want to saved them as one character with ' '.
Any method to get all the whitespace?

[DeMan]

you could try using getchar() et al to get input....

[nickyeng]

getchar() fails.

but get() works.

thanks for the tip.
