In C specifically (i suppose this also applies to C++), what is the difference between
char str[4] = "abc"; char *cstr = {"abc"};
Problems arise when i try and pass my "abc" into a function that accepts char**
void f(char** s) { fprintf(stderr, "%s", ...

These two are equivalent:
char *cstr = {"abc"}; char *cstr = "abc";
Your problem ....
] = "abc"; char str[4] = {'a', 'b', 'c', 0};
The second line declares a pointer to a memory location, which contains the bytes 'a', 'b', 'c', and 0.

But better is to use....
$urlPath ='\\abc\\def\\fg.jpg'
Use mysql_real_escape_string( ) to escape special it (\)
$urlPath ='\\abc\\def\\fg.jpg';
Then you need to escape it again for MySQL because the literal string a connection.
Try this...

Given a bunch of strings I need to find those which match 3 kinds of patterns:
Prefix search - abc* Glob-like pattern - abc:*:xyz Suffix search - *xyz where * is a wildcard (and can match any number of chars).
Now the straight-forward solution is just...

With abc" and "ends with xyz", using these properties as keys?

Hi,
What do people here use C++ Abstract Base Class constructors for in the field? I am talking about pure interface classes having no data members and no non-pure virtual members.
Can anyone demonstrate any idioms which use ABC constructors in a useful...

Can anyone demonstrate any idioms which use ABC! There's no reason to declare them:
Empty and inline => why bother to declare it? Protected => the ABC as a subclass.
From the constructors of each of the derived classes.

I'm banging my head against a wall. I want a regex that matches: empty string, A , AB , and ABC , but not AC . I have this, which works:
/^(A|AB|ABC)?$/
But this is a simplification; in my app A , B , and C are actually long character classes, so I don...

Try this regular expression:
^(A(B(C)?)?)?$
I think you can see the pattern and expand it for ABCD.

Hi,
i want to realize a construct in MS SQL that would look like this in Oracles PL/SQL:

I think you could also to something like
INSERT INTO abc SELECT column1, column2, column3This seems to be simply a copy of one table, right?
Well:
SELECT column1, column2, column3 INTO abc
INTO @asdf, @vcxvcint, @dffgdfg....

On my OS X 10.5.8 machine, using the regcomp and regexec C functions to match the extended regex "(()|abc)xyz", I find a match for the string "abcxyz" but only from offset 3 to offset 6. My expectation was that the entire string would be matched and that...
