Should one use < or <= in a for loop [closed]

Answer 1

The first is more idiomatic. In particular, it indicates (in a 0-based sense) the number of iterations. When using something 1-based (e.g. JDBC, IIRC) I might be tempted to use <=. So:

for (int i=0; i < count; i++) // For 0-based APIs

for (int i=1; i <= count; i++) // For 1-based APIs

I would expect the performance difference to be insignificantly small in real-world code.
