convert int to store in binary file in 1byte

[ycliuwz]

Hi,
Could anyone help me out on this.
I'm trying to store an unsinged int that will at most use 1byte into a
binary file but to no avail.
could anyone help me out on this? thanks in advance

unsigned char is an unsigned integer type that's exactly 1 byte in
size.

You posted the same question three times. (That seems to happen a lot
with groups.google.com; I'm not sure why.)

We must do something. This is something. Therefore, we must do this.

Please stop your rapid reposting -- your message did come through
the first time.

If you have
unsigned int value;
and
value <= UCHAR_MAX;
is always true, then you can just assign value to an unsigned
char variable and write this one to the file
(sizeof (unsigned char) is always 1 [byte]).

Cheers

.... indeed, but would not fputc(value, fp) be even simpler?

Yes, as long as INT_MAX >= UCHAR_MAX; IOW, in nearly all cases :-)
