如何在没有大量代码的情况下处理这个数组?

I'll start by admitting this is for my homework and I don't expect anything specific just a tip perhaps. The input file is just one 30 byte field that contains names. The output file is two fields 30 bytes each. I'll list the code to show what I mean by this. The program needs to read the input file putting the names into an array and then print them to the two fields in the output file. It would be simple enough if the out put file was like this:I'll start by admitting this is for my homework
