printf itself

But it doesn't say what you need it for

I don't understand 'for': I need it to write a program that print its code. Have you see in the example link how cout.form is used? Is there a similar function that work as it?

Is it just for fun? For school? For any practical use? I'm just curious.

try std::string and its sprintf method (I think it has one). Then you can redirect the result to cout.

OK!! It is just for fun. But I think your target in your question was another. Is it so? I'm curious too.....
But I don't find fprintf method in string; but if it's used to write on a file as said before it's a cheat...

No... I don't think so.

sprintf not fprintf. You sprintf what you want to printf into a string and then "printf" it (by redirecting) to cout

Something like:

std::string str;
str.sprintf("Format %s", "xyz");
std::cout << str << std::endl;

std::string str;
str.sprintf("Format %s", "xyz");
std::cout << str << std::endl;

To copy to clipboard, switch view to plain text mode 

Just make sure std::string::sprintf really exists.

it doesn't exist as part of string....(at least in .net); but I wonder where's the "form" method....
