I understand it is about pointer and pointer address of the array. Can somebody explain to me why line 7 should not be as :
Code:
printf("argc:%d\t%s\n",iCount, *argv[iCount]);
I thought *argv[iCount] is the correct way as argv[iCount] is one of the array members address, not the content of the pointer pointing to. But my understanding is wrong! What did I miss? Thanks a lot!
say I have a IP address which is 10.0.0.12, and subnet mask is 255.255.255.240, what is the network address and what is the broadcast address which host lives on?
And could you explain how to get the answer?
thanx in advance! (7 Replies)

And, while the subject is on, how do get a 32 bit pointer in RAM also, in which I can do the same?
I'm using C and Objective-C with gcc on an iBook G4.

If one wants to get a start address of a array or a string or a block of memory via a function, there are at least two methods to achieve it:
(1) one is to pass a pointer-to-pointer parameter, like:
int my_malloc(int size, char **pmem)
{
*pmem=(char *)malloc(size);
if(*pmem==NULL)... (11 Replies)

qd-config - determine flags for compilation and linking
SYNOPSIS
qd-config [options]

To link a Fortran-90 program with the C++ qd library, it is recommended to link with the C++ compiler used to generate the library. The
Fortran 90 interface (along with a C-style main function calling f_main) is found in the qdmod library. The qd-config script can be used
to determine which flags to pass to compile and link your programs.
