Process file lines stream iterator - c++

Question

Hi I have this script below which streams all the data line by line from input.txt
once that is done the streamed data is then copied to the clipboard.
I want to stream one line process and copy that line, then stream&copy the next line ...and so on.
E.G:
open input.txt copy first streamed line to clipboard, run mouse click macro, run paste macro
then
copy second streamed line to clipboard, run mouse click macro, run paste macro...
loop this over input.txt
I have already used /n as a deliminator in the iterator stream to separate each line

This line makes your program work on all the lines of the file (now stored as elements in a vector) in one go.
std::copy(vecOfStr.begin(), vecOfStr.end(), std::ostream_iterator<std::string>(ss, "\n"));
To make it work line by line instead, just iterate the elements of the storage vector individually with a for loop.
for (auto str : vecOfStr)
{
toClipboard(hwnd, str);
// run mouse click macro, run paste macro...
}
