I want to replace dates in a line in a .txt file.
The line might look like this:
1234 24.08 24.09.
Can I find this line by just searching for 1234 and replace the dates 24.08 and 24.09?

If your replacement has the same quantity of characters as the text in the file, then go ahead and seek to the position and overwrite the text (see std::ostream::seekp).
Otherwise, you will have to write to a new file.
Files can't expand in the middle.
