How to create a file of fixed size

[Man4ish]

I am trying to create a file of fixed size. I am using setw() e.g.
43 68 + 169161408
115 287 + 169161408
I am using setw() after first column

cout<<col1<<set w(20)<<col2<<se tw(20)<<col3<<s etw(20)<<col4<< endl;

But still all records are not of fixed length I have calculated the length but in some cases it is coming different.

You will have to create your file and write the necessary characters to it.

Say you want 1000 100 character records. You therefore write 1000 blocks of 100 characters.
