whenever I load the data, the program only retrieve the first line of the file and then it loops. It looks like the problem lies within the load function and insert function because that's where the code loads the data from the file and where the data loaded insert to the array of the code, I tried adding a sign if the code really loops the, and it really did loop. I think the problem is !feof int the load function but i don't know if it really is.
