Help Having trouble reading/writing data through structures

LainStorm (24)
I'm trying to pass a list from a text file through a function using a structure then output the data in a more formatted manner to another text file, though im having a little trouble with a few errors also im not exactly sure how i'd get these two to run in tandem

void getData(President curr_prez); expects a single President but you pass an array of President.
Also there should be no ; at the end.
Also inFile is not declared.
