Suppose you had "int int_array [12]". Then "int_array [n]" would be an int.
argv is declared as "char *argv []" So "argv [n]" is a "char *".
"char *" is what "printf %s" expects and what makes sense, because you are trying to print a string.
"argv [iCount]" is the content of an array slot. The content happens to be an address, because "char *" is an address.
Suppose "argv [1]" is "123456". Then "*argv [1]" is '1', the single character 1. You could do an experiment and change the code to the following and verify this (untested).
The basic answer is that argv[iCount] is compatible with %s and *argv[iCount] is compatible with %c.
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)

How do I get a pointer to any 32 bit address on my hard drive, in which I then could read that memory or write to that memory address?
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)
Trying to do a ksh script that needs to list all ip address between ip address a and b ..
ie.
Ip address A=192.168.1.200
Ip address B=192.168.2.15
So the subnet changes from 1 to 2 but I want to list all possible ip addresses between the 2..

tcl_concat
Tcl_Concat(3) Tcl Library Procedures Tcl_Concat(3)__________________________________________________________________________________________________________________________________________________NAME
Tcl_Concat - concatenate a collection of strings
SYNOPSIS
#include <tcl.h>
CONST char *
Tcl_Concat(argc, argv)
ARGUMENTS
int argc (in) Number of strings.
CONST char * CONST argv[](in)
Array of strings to concatenate. Must have argc entries.
_________________________________________________________________DESCRIPTION
Tcl_Concat is a utility procedure used by several of the Tcl commands. Given a collection of strings, it concatenates them together into a
single string, with the original strings separated by spaces. This procedure behaves differently than Tcl_Merge, in that the arguments are
simply concatenated: no effort is made to ensure proper list structure. However, in most common usage the arguments will all be proper
lists themselves; if this is true, then the result will also have proper list structure.
Tcl_Concat eliminates leading and trailing white space as it copies strings from argv to the result. If an element of argv consists of
nothing but white space, then that string is ignored entirely. This white-space removal was added to make the output of the concat command
cleaner-looking.
The result string is dynamically allocated using Tcl_Alloc; the caller must eventually release the space by calling Tcl_Free. |
