Alright i am trying to read from a file so that it opens into the array temp_array. the idea is to have the data previously added to the file open into the array so i can search it and sort it this is giving me alot of stress it is an assignment. i have looked at other posts but they have not really helped me with this problem. my read from file displays all right now doesnt place it in the array.
