I have the following line in my code, which is supposed to skip commas
and white space and to read a comma seperated value string into the
appropriate variables:
sscanf(temp.c_s tr(),
"%f%*,%d%*,%f%* ,%d%*,%d%*,%f%* ,%f%*,%f%*,%f%* ,%d%*,%f%*,%d%* ,%d", &dt,
&ti, &lsp, &lst, &lsv, &o, &h, &l, &bd, &bv, &ak, &av, &cv) ;
I suspect the format specifiers are incorrect, since I am not reading
the values correctly from the string - could anyone please suggest the
correct format specifiers to :
1). Igone commas
2). skip any white space between the values/commas

This is rather a C question. I think you'll have more luck asking C
questions in 'comp.lang.c'.

Hi, I've got a field that contains a list of rooms.
In most cases, this contains a single ID. However, under some
circumstances, the field may contain a list of two IDs which
are broken by a comma.
For example: BENL LT, RAT LT
At the moment, I've got the VBA bits working on the single
ID stuff, but, should it come across a list like the above,

hi All,
I am parsing a CSV file.
I want to read every row into a char array of reasonable size and then
extract strings from it.
<snippet>
char foo="hello,world,bye,bye,world";
.....
sscanf(foo,"%s%*%s%*%s%*%s%*%s",s1,s2,s3,s4,s5);
<snippet/>
This is giving me junk .

I have the following code:
sscanf(line, "%d", n_ptr) !=1 || n_ptr <=0;
It only partially works. If the user types a character other than 0-9 to
start the string it fails. However as long as the first character is an
integer it will allow letters in the following places

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
