using >> operator

How do I write a function, class (not sure what I have to write to use it) so that I can return a value to an array. Example, cin is programmed to use that operator to put a char in or whatever.

How can I make a function that uses that? Just to demonstrate an example, let's say that I have this:

int function(char data[10])
{
strcat(data," bla bla")

return data;
}

this function would not work since c++ is worse then a nazi when it comes to arrays. Is there a way I can get data using the >> operator? This will help me allot since I have allot of functions I want to write that could use this. Thanks!

Frankly didn't get why you need a >> operator, may be just you need to use this approach:


#include <stdio.h>
#include <string.h>

char* f(char a[])
{

strcat(a, "Appended String\n");
return a;
}




int main()
{
char a[128] = "Initial String\n";//large
printf(a);
printf(f(a));


return 0;
}




Please - rate answer if it helped you
It gives me inspiration when I see myself in the top list =)

I want to be able to use this way since I can get arrays very quickly once I write a class that can do whatever I want it to do. Instead of going trough all the pointer stuff and return special data types to be able to use more then one char.

I remembering replying to this for some reason but there's none shown to it so I must of dreamed of it or something!(I think I'm too much on the computer if I start getting dreams like that!) Unless I din't notice and typed it in the e-mail... not in my sent items though. hmm, mistery:).

you can use ostrstream class.

Then you can concatenate a string with << (not >>)

So you can do:


void function( std::ostrstream& os )
{
os << " bla bla";
}




You can use this to stream in formatted, the same way as you would any other stream.

of course you could just use std::string with append or += but that would only allow you to concatenate in strings.

Your function, by the way, is wrong in two ways. Firstly your passing of data[10] - should really pass char *data.

Secondly you are returning a char* while your function is declared to return an int.

what arrays exactly?
