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..
Which would be:

pgacreate
PGACreate(8) PGAPack PGACreate(8)NAME
PGACreate - creates an uninitialized context variable. The Fortran version of this function call contains only the last three arguments
INPUT PARAMETERS
argc - address of the count of the number of command line arguments.
argv - array of command line arguments.
datatype
- the data type used for the strings. Must be one of PGA_DATATYPE_BINARY, PGA_DATATYPE_CHARACTER, PGA_DATATYPE_INTEGER,
PGA_DATATYPE_REAL, or PGA_DATATYPE_USER
binary -valued, character-valued, integer-valued,
real -valued, or a user-defined datatype, respectively.
len - the string length (number of genes).
maxormin
- the direction of optimization. Must be one of PGA_MAXIMIZE or PGA_MINIMIZE for maximization or minimization, respectively.
OUTPUT PARAMETERS
none
SYNOPSIS
#include "pgapack.h"
PGAContext * PGACreate(argc, argv, datatype, len, maxormin)
int *argc
char **argv
int datatype
int len
int maxormin
LOCATION
create.c
EXAMPLE
Example:
In C:
void main(int argc, char **argv) {
PGAContext *ctx;
:
ctx = PGACreate(&argc, argv, PGA_DATATYPE_BINARY, 100, PGA_MAXIMIZE);
:
// Set options here
:
PGASetUp(ctx);
:
// Run the GA here
:
PGADestroy(ctx);
}
In FORTRAN:
integer ctx
:
ctx = PGACreate(PGA_DATATYPE_BINARY, 100, PGA_MAXIMIZE)
:
c Set options here
:
call PGASetUp(ctx)
:
c Run the GA here
:
call PGADestroy(ctx)
stop
end
