Thread: issues reading a file.

hello all. I am in the proccess of writing a program for my astrophysics club. to sum up the function of the program basically, the program simulates taking pictures of the universe based on its location and other details which is read from a .txt file then outputs various magnitudes (determined by clarity of the photo) based on various filters, in a table. Writing the program, everything seems to work the way it needs to, except in the .txt file, nothing is seeming to be read past the 1900th number.

At first I thought it was because the range of my rows were too small, so I changed it from a const int to a const long long; however the program still reads to the 1900th number. I was wondering if there was a way to modify the program so that all the numbers would be read and appropriately sorted.

I'm not sure if this helps, but I am using netbeans v7.1.2 as my ide and cygwin as my complier. Also, for the final version of the program I want to include 3 more .txt files , for a total of 5 .txt files, not just the 2 I am posting here.

Hm... there seems to be an issue uploading directly to the forum so here's a link where you utilize the .txt files. 4shared folder - My 4shared
