Speaking of the order of parameters, return addresses, local variables and other block statements, how are they pushed inside the stack frame and how that particular order works? I'm having a bit of trouble understanding this concept.

How does sqrt function really work ? Does it go by any logical theorem to get the result.
Is there any way i can access the code of libarary function such as sqrt?
You can download the source code from the libc, which is open source: http://www.gnu.org/software/libc/download.html

What sorting algorithm does qsort use?

Closed 9 years ago.
Silly question perhaps, but is there any guarantee that the qsort() routine in the C standard library really implements the QuickSort algorithm?
Since there is nothing in the standard that nominates QuickSort specifically, no.

What does 'sizeof (function name)' return?
(4 answers)
Closed 10 years ago.
I tried sizeof(printf) , sizeof(foobar) etc. where foobar is a user defined function. It returns 1 without any warning or error. Why 1?
The size of functions is not well defined in C, so the value is meaningless.
