Can someone execute this program?

Question

Can someone execute this program for me and tell me if it works correctly? My DOS is acting funny.
look for these things:
- accepts input from keyboard and places them into an array
- continues to accept names until a blank name is entered
- array can contain up to 15 names
- after all names are entered, it displays the contents of the array
and writes them to a file
- output should be in 2 columns
if you see a problem, please tell me how to fix it.

Ok, here is what I came up with. I commented most of what I changed and gave a reason for changing it. My changes aren't perfect and it still needs to be tweeked. When you run the program you have to hit the enter key every time once before you type a name. When you are done typing names hit the enter key twice and it will output the names entered into the array. Like I said, it isn't perfect, and that part you will need to fix.
