C++ outputstream remove stored data

Question

At the moment I am storing some data into an output stream like so

std::ostringstream oss;
std::string fileData;

for(int i = 0; i < 4; i++)
{
    oss << i;
    fileData += oss.str();
}

now the output is this

How can I clear all the data inside my oss variable so this doesn't happen?

P.S. I know I could just declare a new outputstream every time but that seems quite extreme.

Declaring the `ostringstream` inside the loop isn't "extreme", it's proper style. — Potatoswatter, Feb 20 '14 at 00:09
Your output has got to be wrong because you have an index that goes from 0 to 3 inclusive, and the output goes from 1 to 4... — Alexis Wilke, Feb 20 '14 at 00:37
I just typed this out as a example, it isn't my actual code :) — Canvas, Feb 20 '14 at 10:46

You can replace it with an empty string object:

oss.str(std::string());
