发帖数: 114 | 1 Hi all,
I want to append new column data to a data file. The data has been formated
in a tabbed way (very clean data without any missing/empty cells). This is
usefull when I run my c/c++ code and save data each time as one or more
columns. Ideally, it will be done within c/c++ code with fstream, but it is
ok to use stript split single (or 2 column) column data into multiple
columns.
e.g.
file1:
1 2 3
2 3 4
5 6 7 | E*V
