Question

I need to get names from one file and write them to another.
Lines of first file look like this:

a001   0 0 :N
a0100  0 0 :N
a1000  0 0 :N

Where a*** – name, first 0 – coord X, second 0 – coord Y, and :N – doesn’t matter.
Second file that I need to write must contain names from first file and instead first 0 and second 0 must be randoms numbers.
In the end, second file must looks like this:

a001  10  150 :N
a0100 0   20  :N
a1000 130 0   :N

How can I do this?

Answer 1

To read, try C++’s stream operators to read tokens: C++ Reading file Tokens

To write, try C++’s stream operators with setw to line up the columns.
