This doesn't output the full 0 - 255 range of characters. I need to print them all to screen. Is it a problem with ANSI?Code:#include <curses.h> int main() { initscr(); raw(); int a = 0; do { addch(a); refresh(); a++; } while (a < 256); getch(); endwin(); return 0; }
Not all characters in that range are printable.

Yes they are *blinks*
Try ZZT for instance; an oop based programming gcs
So, anone else (not using linux, who knows about the ansi system)?

I fail to see how it can be a problem with ANSI.It's not really a problem with ASCII either.I think the problem is that you don't know what you're talking about. Try being a little less arrogant. It's a safe assumption that some people know more than you.

Excuse me? How dare you call me arrogant?
I disagree. I think that with a CERTAIN method (that I don't know) ALL of the chars are printable. I've seen them all printed in the ZZT dos program. In fact, if you run that code I posted in the start of the thread, you will see that all the chars beyond 126 ARE printed. At least, they are on my Windows ME system. And before anyone attacks me for using windows, I already know Microsoft is a bunch of ......... But I have always refused to use unix as I don't have the time to learn it. Thank you.
Keep it friendly, or I'll close the thread
Whether you are using Microsoft or Linux will not alter the fact that it is certainly true that not all of the characters represented by the values 0 - 255 are printable in the simple sense of the technique.
Consider the value zero, a NUL character, doesn't print. You may have had something that prints a splat when it can't translate what you are saying, that is not the same thing as printing the actual character.
If it helps you, I'll add the *blinks*.

Thats not ASCII, ASCII is 7 bits, (Extended ASCII added use for the eigth). Also, notice that page specificly mentions DOS/Windows, in Linux all I see is a box with the hex inside of it for the unprintable characters.
http://en.wikipedia.org/wiki/ASCII
That is ASCII, and as its states, their are 95 printable characters in the ASCII code set, which is the default for C and C++, as far as I know. I believe some regions changed some of the character codes though, to cover accented characters, which is why you might have to use trigraphs.
Want to check it out? try
look at this for the output I got in Linux. You will notice you don't see any thing but blank spaces at first.Code:#include <iostream> using namespace std; int main() { char current = char(0); for (int i = 0; i < 128; i++) { current = char(i); cout << current << '\t'; if (i%10 == 0) { cout << endl; } } cout << endl; }

If any part of my post is incorrect, please correct me.

1. I am using Win32, not linux, so please if anyone knows about windows, help me
2. I very much *do* want to print the characters that I *know* are able to be printed. May I have some help with *that* please?
> I am using Win32
And which compiler?
I can see from your original post that you're using a curses library - which one is that?
As others have said, anything outside the range 32 to 126 is horribly implementation specific, so we need more details if there is to be any chance of further progress.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
Using Windows XP, I was able to print symbols for 1-6, 11, 12, 32-254. The other character codes used their ASCII behavior. I did note that you can see the symbols for 7,8, and 13 by saving them to a file and then opening the file with the edit command. Seeing as the edit command can do it, there must be some way to get C++ to do it too.
I'd like to apologize for my previous post. It was a bad day, and I was unnecessarily gruff.

As its been said, the characters outside that range, are implementation specific. You might want to find the doc's dealing with your compiler. Also, why must you be able to print them out? I don't see any reason why you need to print them all to a screen.

Ok...I am using DevvC++ bloodshed and pdcurses from http://gnuwin32.sourceforge.net/packages/pdcurses.htm
