ANSI output

Pianorain: no need to apologise.

There are only a certain number of ASCII characters that can be printed, given any OS and any compiler that is based on ASCII.

There may be a certain subset more that can be printed, based soley on OS and compiler.

Code:

        ☺       ☻       ♥       ♦       ♣       ♠

        ♫       ☼       ►       ◄       ↕       ‼       ¶       §       ▬
↨       ↑       ↓       →       ←       ∟       ↔       ▲       ▼
!       "       #       $       %       &       '       (       )       *
+       ,       -       .       /       0       1       2       3       4
5       6       7       8       9       :       ;       <       =       >
?       @       A       B       C       D       E       F       G       H
I       J       K       L       M       N       O       P       Q       R
S       T       U       V       W       X       Y       Z       [       \
]       ^       _       `       a       b       c       d       e       f
g       h       i       j       k       l       m       n       o       p
q       r       s       t       u       v       w       x       y       z
{       |       }       ~       ⌂

That was the output from the program below on a Windows 2003 Small Business Server OS using Microsoft Visual C++ Toolkit 2003.

Code:

#include <iostream>

int main()
{
	for (int x = 0; x < 128; x++)
	{
		std::cout << (char)x << "\t";
	}
	
	std::cin.get();
	return(0);
}

So no. Not every character in ASCII can be displayed on all implimentations.

int main()
{
  int y ;
  //-------------declares the colours were going to use -------------//
  
      HANDLE h = GetStdHandle ( STD_OUTPUT_HANDLE );
    WORD wOldColorAttrs;
    CONSOLE_SCREEN_BUFFER_INFO csbiInfo; 
    

    
  //--------------------generates the ASCII list--------------------//
  
  for ( int x = 0; x < 257; x++ ) { // declares x , adds 1 to x while x is smaller than 256 //
   
              SetConsoleTextAttribute ( h, FOREGROUND_BLUE | FOREGROUND_INTENSITY ); 
   
    cout<< x <<".) " ;
    
              SetConsoleTextAttribute ( h, FOREGROUND_GREEN | FOREGROUND_INTENSITY ); 
    
    cout << (char)x << endl ; // shows wich number corrospontents with the ASCII number // 
    
  }
  
  // some copyright :P  
  
            SetConsoleTextAttribute ( h, FOREGROUND_RED | FOREGROUND_INTENSITY );    
      cout << endl << "written by " ;
          SetConsoleTextAttribute ( h, FOREGROUND_BLUE | FOREGROUND_INTENSITY );  
      cout << "MystWind "<< (char)184 ; // (char)184 stands for nr. 184 in the ASCII listing ; copyright.
      

  getch(); // this doesn't closes the program until you press a key.
}

so whats the problem with just 95 characters being displayed?
I can;t compile your program though , because of the cursus libary

Did that ever strike you as needlessly complicated, Myst?

**sufthingol** · 03-09-2005

Apparently there is a video mode that let's you display those glyphs directly. A programmer known as Tim Sweeny did it in his dos program ZZT. I wish I knew how he did it. He was using Pascal btw.

Somehow ZZT made it onto the list of "Top 100 DOS Games". That better be why.

**Hunter2** · 03-09-2005

I can't say I know how this can be done without creating a font yourself and doing some manual rendering, or using some Windows API functionality (or other 3rd party libraries, like the curses one you're using perhaps). After all, there are characters that hold special functions such as '\0' (as has been mentioned), '\a', '\t', '\b', and all the other escape sequences as well. If you try outputting any of them, they will almost certainly not display single characters as you might expect.

He also went on to help start Epic Megagames, now known simply as Epic Games, the makers if the Unreal Engine (and series).

**sufthingol** · 03-10-2005

I have found out how to do it.

Code:

int a = 0;
  do
  {
    addch(a | A_ALTCHARSET);refresh();
    ++a;
  }
  while (a < 256);getch();

NO its NOT needlessly complicated : check the out put , its better than any other ASCII output listing programs.
