    assembly in c++

    Does anyone knows how can I create and output to the screen something that is not a ASCII symbol.... for exemple a smile.....
    I belive you can do that in assembly and call that fuction latter on in C++, unfortunetly I forgot all assembly I learned 15 years ago...
    Can anyone also supply me some short examples or some good tutorials for that.... i've just looked on the web and I've got too many asm tutorials, can anyone tell me witch one might be the most sutable for my needs...

    Thanks

    I am guessing this isn't what you are talking about.. (No asm to be seen!)
    Code:
    #include <iostream>
    
    using namespace std;
    
    int main()
    {
            cout << static_cast <char> (1) << endl;
    
            cin.get();
    
            return 0;
    }
    What exactly is it your trying to do? Do you mean you want to create a graphic that can be displayed to the console, but is not an ascii character. If so, you probably don't need ASM to do this.

    Man, you are way off. It has nothing to do with assembly. It has to do with how your OS translates numerical values into a visual symbol. To illustrate, I will give you a peek into my world of 'subsystem assembly programming'. Note that the code *is* copywrite protected.

    Code:
    int main()
    {
       for(int i = 0; i < 256; ++i)
      {
       printf("%c", i);
      }
     system("pause");
    }
    Code:
    if( numeric_limits< byte >::digits != bits_per_byte )
        error( "program requires bits_per_byte-bit bytes" );
    24bbs.cpp

    Talking Right! ...Copyright!

    Note that the code *is* copywrite protected.
    Sebastiani, I hope you're not serious.

    1- I don't think you are the first person to "create" this code snippit. In order for a copyright to be valid, the material has to be unique... I could copyright a poem (if I were a poet), but I cannot copyright the phrase "Hello, how are you?"

    2- If you don't want anybody using your code, don't post it on the Internet! (You don't loose your legal copyright by publishing on the net, but you do loose practical control.)

    I was trying (although perhaps not well enough) to be sarcastic.

    What a goober.

    Code:
    if( numeric_limits< byte >::digits != bits_per_byte )
        error( "program requires bits_per_byte-bit bytes" );
    24bbs.cpp

    Wow.


    dhrodrigues, ASCII isn't just letters, punctuation and numbers.
    There are some other symbols in there too, including a couple smiley faces and shaded blocks.
    I suspect you're not writing windows programs here, so have a look at the ASCII characters and use them. Use sebastiani's code to see them all.

    Extended ASCII characters are not standard.

    including a couple smiley faces and shaded blocks.
    Note that these special "characters" are system-dependent. The ASCII standard goes from 0 to 127. 128 - 255 will vary. Here's an ASCII chart.

    Thank's for confirming you were joking, Sebastiani. I was worried that you might be an SCO employee!
