I would like to take a text file, which has been saved with various special characters ('e.g. $$') and identify the positions that these characters occupy. Then, I would insert values into those positions. So the file may look like: line $$ 1 $$ line 2
So I would need some way to identify positions 6 and 11, then insert text at those locations.
I've tried various things such as reading the file in a string and converting to a char array while using strfind, but in each case, there is an issue. What would be the best way to overwrite the $$'s with values?
Thanks
