vector<int> vec_num; for(int i=1;i<argc;i++){ vec_num.push_back(atoi((char*)argv[i])); } sort(vec_num.begin(),vec_num.end()); copy(vec_num.begin()+((vec_num.size()-5)/2), vec_num.end()-((vec_num.size()-5)/2), ostream_iterator<int>(cout, "\n"));

Anyway, a 5 is a 5 ;P. Btw I think I should learn a new language to reply to your Friday Question. Replies representing all other languages are just there in seconds you post your question.we can't make our replies unique unless I try for a deliberately different technique of the same language.:-D

Given a set of numbers passed to the command line. The number of number is always odd. The program should sort them and output the 5 numbers in the middle. For example, if there are 9 numbers the output should be sorted numbers from indices 2 to 6. e.g.
c:> med5 67 89 12 1 8 1 3 5 7
3
5
7
8

Here's some C#.
System.Collections.Generic.List<int> list = new System.Collections.Generic.List<int>
(
System.Array.ConvertAll<string,int>
(
args
,
delegate ( string s ) { return ( (int) System.Convert.ChangeType ( s , typeof(int) ) ) ; }
)
) ;list.Sort() ;
foreach
(
int i
in
list.GetRange
(
args.Length/2-2
,
5
)
)
{
System.Console.WriteLine ( i ) ;
}This points up two shortcomings of the current (V2) implementation of .net: 1) System.Array doesn't have a GetRange() method 2) Sort() returns void -- returning a reference to the object would be more flexible If these shortcomings were corrected, the above code could be:
foreach
(
int i
in
System.Array.ConvertAll<string,int>
(
args
,
delegate ( string s ) { return ( (int) System.Convert.ChangeType ( s , typeof(int) ) ) ; }
).Sort().GetRange
(
args.Length/2-2
,
5
)
)
{
System.Console.WriteLine ( i ) ;

Not Vaporware Beta? :-D As VB is just a "prototyping language", it makes sense to use it as a test bed for Linq, before putting the final implementation in C#.
Do you now that the Silverlight Compiler is written in VB.Net???? You should think twice before you say that VB is used only for testing purposes.
