....
somewhere, a newbie is dying ...
Is there anybody out there who can help me get the right input
for the following segment? I am trying to read entire records
of 5 (2-digit) integers at a time. It would be best to read the
integers into their own 5 respective variables.
I thought I had it. I've redone my program so many different ways
I am coming to the same conclusion I did when I tried to do it
several years ago: that it cannot reasonably be coded in any popular
language. I just now gave up on reading each individual integer
because I was getting output that looked like my
fscanf(fileptr, "%i", &n); statement was reading entire records instead.
My first record is: 17 40 41 42 46
The following code seems to go only once thru the first 2 FOR loops
(on step-through) and bombs about 46 times thru on the 3rd FOR loop,
with a:
"unhandled exception -- access violation" error.
Using MVC/C++ 4.2 -- is this too "old."
Please HELP (WTH IS GOING ON???)
