That's odd. With g++ 4.4.5 on an x86-64 machine in 64-bit mode I get:
---
125 1
126 1
127 1
which is what I would expect. That is, i is a (signed) char, and when it
goes over 127 it becomes a negative number, so the loop terminates.
That would be the expected result if char was unsigned.
Not exactly, no? An unsiged char goes to 255.
Best regards.
