Maximum characters in string

[daph]

Hi,

Anyone here know the maximum number of charaters possible in a string?

Ex: char string[MAX];

Thanks,

Daph

C itself has no limit to the length of a string.

Your C compiler / OS may have other ideas though.

And it depends on whether such an array is global or local to a function.

i compiled it in Turbo C & C++ Compilers

global is Maximum of char string[65534]
local is Maximum of char string[65535]

i've no other compilers availble in this net center

DJ911, that's the 64K limit of 16-bit programming (I think). I suspect the difference of 1 is a mistake. In either case you can store 64K of characters MINUS ONE, because the string has to be terminated.

please check it on older version of Turboc201
see the different of Globla & Local ur self

I'm not disputing you saw a real difference. I'm disputing that there should be a difference. Even compilers aren't right about everything! The only difference between global and local in a 16bit system is which segment is used (ds, ss), and that makes no difference to the available size of a segment.
Incidentally, have a go at making a local string 65535, or even 65534 bytes long and filling it with characters. See what happens. I'd almost be prepared to bet it fails. After all, the stack segment has to contain the odd function return address too.
