I admit it is odd. I create the vertices and faces by a script in C. I save the
vertex and face vectors within loops directly into files by fprintf. Then, I get
the numbers at the end of the loops. AT  this stage, I cannot append the numbers
at the beginning of the vectors saved into files.

Therefore, my output is two files and the corresponding numbers.
