Information from a file and structs?

Hi, I'm new to C programming and am having trouble with a program I'm trying to write. The goal of this program is to take the following information (which I have stored in a file) and display the locus (which is AJ002502), length of sequence (all of the ACT&Gs), and then print out the sequence. I'm trying to modify one of my existing programs but am having trouble. Any help would be greatly appreciated.

Thanks
