Why is iostream::eof inside a loop condition (i.e. `while (!stream.eof())`) considered wrong?
...
Because iostream::eof will only return true after reading the end of the stream. It does not indicate, that the next read will be the end of the stream.
Consider this (and assume then next read will be at the end of the stream):
while(!inStream.eof()){
int data;

Approximate cost to access various caches and main memory?
... @LewisKelsey: Yeah, that's all true for writing. I thought this was for reading (Data Source Latency), which is more latency-sensitive. Reading a line never requires an RFO, just a request to share. So shouldn't a line that's already in Shared state somewhere, just hit in this socket's L3 witho...

Getting number of elements in an iterator in Python
... you a better way to accomplish your actual goal.
Edit: Using list() will read the whole iterable into memory at once, which may be undesirable. Another way is to do
sum(1 for _ in iterable)
as another person posted. That will avoid keeping it in memory.
