Reading a string from a file and outputting it into another file.

[liyana]

Hi,

I am new in C++ and i am not sure how to do this.

I have a file (a.txt) which contains infos like this:

'abcd123'
'd12345-01'
'12345'

I would like the output in another file (b.txt) to contain only string of certain line, let say:

abcd123
12345

But i am not sure how to actually scan the infos by x-coordinate. i do know that C++ can use getline to read by lines. how about the x-axis?

your problem is not clear.why do you need x axis in reading file contents?
