Re: To get filename as input

Asking the same question again will not get you the answers. Read the replies to your previous thread, I'm sure you will find the help you need there somewhere.

What filename?

problems in binding INADDR_ANY

Hi all,
My application was binding to a specific address earlier, but now there is a requirement of binding it to INADDR_ANY, the problem which i'am facing while binding to INADDR_ANY is...the client can able to listen to the data coming from main IP of server i.e
for ex: my server system is having 7 IP's like 172.16.8.1 to 172.16.8.7, and main IP is 172.16.8.1...if client is connecting with 172.16.8.1 it works fine...but if it is connecting with other IP's, client is unable to listen to the data coming from other IPS.
Can any one suggest me a solution for this

If you bind to INADDR_ANY how will the other end know what address to send to?

Find Algorithm [STL]

Please consider this example:

#include <vector>  
#include <list>	   
#include <algorithm>	   
using namespace std;
...
list <int>  nums;
list <int> ::iterator nums_iter;

nums.push_back (3);
nums.push_back (7);
nums.push_front (10);

nums_iter = find(nums.begin(), nums.end(), 3); // Search the list.

if (nums_iter != nums.end())
{
    cout << "Number " << (*nums_iter) << " found." << endl; // 3
}
else
{
    cout << "Number not found." << endl;

}

Here the elements are of type "int". So we can directly make a "find". But what if the pushed elements are objects? or struct variables?
for example:

typedef struct myStruct
{
 int x;
 int y;
}myStruct_t 

myStruct_t mySObj; mySObj.x=10;mySObj.y=20;

list <myStruct_t> lst_mySObj;
//Push a lot of mySobj into lst_mySObj list.

list <myStruct_t>::iterator mySObj_iter;

How do I do the rest of the rest of the things?
Like this :???
~~mySObj_iter = find(lst_mySObj.begin(), lst_mySObj.end(),mySObj.x );~~
Not sure Unsure | :~

In this case,class/struct should have operator == defined.
Which takes care of rest of the things.
Let me modify your code like this,

typedef struct myStruct
{
int x;
int y;
bool operator == (const myStruct rhs)
{
   return ((x==rhs.x) && (y== rhs.y));
}
}myStruct_t ;

Now your code work with this structure.

Nice, it compiles now. Thanks. Now, the "find" doesn't work ! anyway thanks I've moved a step up. Smile | :)

list <myStruct_t> lst_mySObj;
 
for(int i=1;i<=20;i++)
{
 myStruct_t mySObj;
 mySObj.x =i;
 mySObj.y=i;
}
myStruct_t mySObjFind;

mySObjFind.x =5;

mySObjFind.y=5;


list<myStruct_t>::iterator mySObj_iter;
;
;
mySObj_iter = find(lst_mySObj.begin(), lst_mySObj.end(),mySObjFind );
;
//   	printf("\nHere%d",(*mySObj_iter).x);//iCrash!
;
;
/*if (mySObj_iter != lst_mySObj.end())
{

   	printf("\nHere%d",(*mySObj_iter).x);  Never enters here..

}*/

How have you defined the operator == on your struct?

Astricks7-Feb-07 19:49

7-Feb-07 19:49

Yes:

typedef struct myStruct
{
int x;
int y;
bool operator == (const myStruct rhs)
{
	printf("\n%d,%d-%d,%d",rhs.x,rhs.y,x,y);

	return ((x==rhs.x) && (y== rhs.y));
}
}myStruct_t;

It looks ok, but normally we would not pass a copy, try changin it to this
bool operator == (const myStruct& rhs) not that it should make a difference.

Doesn't work still

Astricks7-Feb-07 20:08

I changed it to reference type, but still doesn't work Frown | :(

I tried to print them :

for (mySObj_iter=lst_mySObj.begin(); mySObj_iter != lst_mySObj.end(); mySObj_iter++)
{
	printf("\n%d",(*mySObj_iter).x);
}

Even this doesn't work Hmmm | :|

I think you forgot to add the object to list, Following code works perfectly for me,

typedef struct myStruct
{
	int x;
	int y;
	bool operator == (const myStruct rhs)
	{  
		return ((x==rhs.x) && (y== rhs.y));
	}
}myStruct_t ;

		   
int main()
{
list<myStruct_t> nums;
list<myStruct_t>::iterator nums_iter;
for(int i=1;i<=20;i++)
{
	myStruct_t mySObj; 
	mySObj.x =i; 
	mySObj.y=i;
	nums.push_back(mySObj);
}
	myStruct_t mySObj; 
	mySObj.x =5; 
	mySObj.y=5;
nums_iter = find(nums.begin(), nums.end(), mySObj);
printf("\nHere%d\n",(*nums_iter).x);
 // Search the list.
if (nums_iter != nums.end()){
    cout << "Number " << "a" << " found." << endl; 
	// 3
}else
{    cout << "Number not found." << endl;}

}
