What I'm doing is reading an inputfile and doing linked list. When I output it, only the second data which is nicole's info is output in the outputfile. Also, the output would look like this:

I am completely confused as to why this is happening and outputting the same thing infinite times.

The two primary problems are that head is never updated in main, and your output loop never sets stdPtr to stdPtr->next. Given your description of the problem, as well as syntax errors, I find it difficult to believe that the provided code is the same code that you're executing.
