Hi Prasanth, you have gotten offers of help and concrete suggestions.
However, you have repeated the same program listing a few times now,
apparently without trying the feedback you have gotten so far on it.
Please take some time to try out and investigate the suggestions that
have been made already, such as making sure the fscanf format
conversion is correct.

Samples in what format? The program listing you provided reads a text
file containing whitespace-delimited integers. We haven't seen your
file "buffer" so we have no idea if that's correct. Even if it is,
your program is attempting to load integers into a ColumnVector which
is effectively an array of floating point variables.
