Hi,
Is there a function in C that computes the number of characters in a
string.
I want to be able to compute the number of chars in the string '1 3 4
5' by suppressing the ' ', so length should be 4 instead of 7...
Thanx

Yes, it's strlen(). Don't forget #include <string.h>.

What is the exact text of the problem you have to solve for your course?
My guess is that you are taking the wrong approach.
Best regards,

Can it be, that the OP has wide char strings?
In this case wcslen() is what he/she needs
Just a wild guess

There's no such standard function, but it's easy to write one
yourself. Just lookup the various is...() functions declared
in ctype.h and do something like:
#include <ctype.h>
int strGraphCount( const char *s )
{
int res = 0;
for( ; *s; ++s )
if ( isgraph( *s ) )
++res;
return res;
}

Perhaps (that would be a problem for the course in advanced C
programming, I presume).
The OP's question smells like homework - I guess that's what I am trying
to say.

Uck, that was a real mistake, thanks for correction. ++res;
return res;

I'm trying to clean up a large database in Access. I have one field for

The problem is that the data is very dirty. So some addresses will be
standard "456 XYZ Road," while others won't have a number and will just say
"XYZ Industrial Park," meaning I can't just use Instr to search for the
first space because sometimes the...

I see other posts where some say fields that will hold a number with
leading zeros should be stored as text instead of numbers.
This is very inefficient though, as a string of digit characters takes
up much more memory than a 32bit or even a 64bit int.
Storing as a number still allows for formatting when displaying the
number, correct?
I am creating a table and would like opinions regarding this please.

If the first char is 1 = output is $1.00

Hi
If I use len() on a string containing unicode letters I get the number
of bytes the string uses. This means that len() can report size 6 when
the unicode string only contains 3 characters (that one would write by
hand or see on the screen). Is there a way to calculate in characters
and not in bytes to represent the characters.
The reason for asking is that PyGTK needs number of characters to set
the width of Entry widgets to a...

Let's say I have a cstring: char str = "Hello world";
and I have a needle: char n = "wo";
I find that the needle starts at the 5+1 position of the string.
How am I going to copy the characters up to this point, using the
<cstringheader?

Using <string(c++ string) it is possible in two ways:
1) for (int counter = 0; i < str.find(n); i++)
tmp += str;

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
