I'm just learning c++, and coming from c, some function calls I'm seeing in the book confuse me:
char a; cin.get(a);
In C, this couldn't possibly work, if you did that, there would be no way to get the output, because you are passing by value, and not...

The implementation passes by pointer internally.....
It is similar to passing a pointer (pass by pointer) in C, but with a nicer syntax and more safety (compile-time checks) .
Reference types work like that (pass by reference, instead of passing by value) .

Hi
I have to pass the address of a member fn taking one argument to the std::for_each. how do i do this?
class A{ void load() { vector<int> vt(10,20); std::for_each(vt.begin(), vt.end(), &A::print); //It didnt work when i tried mem_fun1(&A::print...
Answer Snippets (Read the full thread at stackoverflow):
Also, print doesn't manipulate any of the member variables, just make it static :
class A{ void load() { vector<int> vt(10,20); std::for_each(vt.begin(), vt.end(), A::print); // static functions... .
What you have in vt are integers not objects of type A .

"order by" in query is taking to much time in MySQL. SHOW PROFILES shows that the time is taken by the sorting process. Is there any setting/workaround that will decrease the sorting time ?

If you don't have an index....
You may be able to increase the speed of returning sorted results by adding an index on the column(s) that you want your results ordered by .
Adding appropriate indexes for the fields you're ordering by should do the trick .

Is it possible to simply take a picture and save it somewhere using a QTCaptureView and Apple's built-in iSight? I've seen lots of tutorials on recording video but none on simply taking a picture. Any help or guidance is appreciated!

My work computer connected through LAN is taking forever to login. It takes 10 minutes to login to the computer.
How can I debug this issue?
UPDATE:
Turns out it was some services that were running in the background that was causing this problem.
