    #define question

    can i #define a character.
    for example the value of the char. 'N' is 78
    'E' is 69
    'N' + 'E' = 147
    i want to #define NE 147
    is this possible??

    you could do something like this

    Code:
    #include <stdio.h>
    #define ADD_CHAR(a,b)(a+b)
    int main()
    {
    	printf("%d",ADD_CHAR('N','E'));
    	return 0;
    }
    then it would work for any letter.

    just a thought
    All spelling mistakes, syntatical errors and stupid comments are intentional.

    Yes
    you can #define NE 147
    so 'N'+'E'==NE would be true.

    #define QUESTION ( 2B || !(2B) )
    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.

    Hate to be the one to tell ya this Salem, but your code is invalid.
    Code:
    #include <stdio.h>
    
    #define QUESTION ( 2B || !(2B) )
    int main ( void )
    {
    	return printf("%d", QUESTION );
    }
    Compiling...
    test1.c
    c:\windows\desktop\test.c\test1.c(6) : error C2059: syntax error : 'bad suffix on number'
    c:\windows\desktop\test.c\test1.c(6) : error C2146: syntax error : missing ')' before identifier 'B'
    c:\windows\desktop\test.c\test1.c(6) : error C2059: syntax error : 'bad suffix on number'
    Error executing cl.exe.

    test1.exe - 3 error(s), 0 warning(s)


    ...And then, as I was typing this message, I actually _read_ the code. Good one, you got me there. Good show!

    Cool

    How about writing a whole novel in C?
