Since you've not specified the language, I've assumed that you need a bash script.

[user@host ~]$ cat>file
[user@host ~]$ cat
#! /bin/bash


while read line
    (( i++ ))
done < file

echo ${namesArr[@]}
[user@host ~]$
[user@host ~]$ ./

If you don't want the Names' file to be among the files to be worked upon, you could also try
awk 'BEGIN {while (getline A[++i] < "file"); . . .

In bash, you might want to consider the mapfile builtin.
