I have a long int variable that I need to convert to a signed 32bit hexadecimal string (8 characters) (char array) without the "0x" at the start?
How would I go about doing this?
Thanks.
I want to define the block as a string, then create the lambda.
The following example does not work.
Is something like this possible?
code_string = "|x|x*2"
l = lambda {eval(code_string)}
l.call(3) => 6
std::string x(x);
This crashes very badly on my compiler. Does this mean I should test for this != &that in my own copy constructors, or can I assume that no client will ever be so stupid?
According to CI's docs, CodeIgniter uses a segment-based approach, for example:
example.com/my/group
If I want to find a specific group (id=5), I can visit
example.com/my/group/5
And in the controller, define
function group($id='') {
...
}
Now I want to use the traditional approach, which CI calls "query string" URL. Example:
example.com/my/group?id=5
If I go to this URL directly, I get a 404 page not found. So how can I enable this?

My emacs hangs (Ubuntu 9 + emacs 23 + pyflakes) when I type """ quotes for string blocks.

Anybody hot around the issue? It really frustrating experience.
Is there a way in objective-c/Cocoa to alloc an object when the class name isn't know until run-time. I seem to remember something about this a while ago, but can't find anything on it now.
Something like:
[[@"MyClass" alloc] init];
I seem to recall a function that would return some kind of class id based on a string that can then be used to alloc the object.

Assume:
Elf_Section_Header *sectionHeaderTable //points to the start of a ELF section header table
Elf_Section_Header *symtabHeader //points to the start of the symtab section header
Why doesn't the following point me to the associated string table section header?
Elf_Section_Header *strTabSectionHeader = (Elf_Section_Header *)((char *)sectionHeaderTable + (symtabHeader-strtab_index));
'strTabSectionHeader-type == SHT_STRTAB' is equal to false
How should I point ot the strTabSectionHeader?

['1.1.1', '1.2.1', '10.1', '2.1'] - ['1.1.1','1.2.1','2.1','10.1']
