[terminal something error]

Hi, something strange happened today i made a c program to print all the ascii characters but when i run it the terminal, the terminal gets all screwed up, even if i run it without x on  the console!!

this is a screen-shot of my desktop with the code and the terminal screwed up characters.

the code:

#include <stdio.h>
main(){
char n=127;
while (n){
n--;
printf("%c",n);
}
}

In short: terminal input/output is pure magic (try reading the whole howto), but <enter>, 'reset', <enter> should fix it.

Re: [terminal something error]

You are trying to print the entire ASCII table. If you look at the ASCII table http://www.asciitable.com/, the lower range characters (less than 32) are not really printable characters, are they?

no but that's not the problem, when the program returns the part:

bernardo@sonyarch

is written as something strange, its like the key map have changed.. if you look closely at the screenshot you can see the cursor after some weird characters.

if i try to write only numbers come out right everything else is pretty weird.

its pretty easy to fix i just had to close the terminal and run it again, i just wanted to know what was going on... the symbols you are seeing correspond directly to chars..
