i''m working on a drawfont class, but i need the index of the ascii character code. like is there a function where you would pass "a" and it would return lowercase a''s ascii code?

int __toascii( int c );

Return Value

__toascii converts a copy of c if possible, and returns the result.

Parameter

c = Character to convert

Remarks

The __toascii routine converts the given character to an ASCII character.

What language?

If you''re using c/c++ then if you interperate the "a" as a char type you have the ASCII code there already. If you''re using a char* as your string. (say a variable called "text" nice obvious name, thats a char* (i.e. string)) containing the text "hello world". Then

text[1] 

would return the char ''e'' (or in actually fact the ASCII code for ''e'', 101.

Hope this helps (if you''re using c/c++)

oh wow that makes things nice and easy thanks C++

billybob - you could also write your own little function in your program.


int asciicode(char c)
{
return c;
}

would work fine and return the ascii code everytime for the character you wanted.

That wouldn''t be how __toascii works SteveBe.

Ascii codes are 7-bit, so you would want to return c & 0x7f.
Also c is an int, not a char.

Characters above 0x7f in "ascii" tables are non-standard.

char __toascii(int c)
{
if ( ( c & 0x7f ) == c ) return c;
else return 0;
}
