After reading Hidden Features and Dark Corners of C++/STL on comp.lang.c++.moderated, I was completely surprised that the following snippet compiled and worked in both Visual Studio 2008 and G++ 4.4. Here’s the code: #include <stdio.h> int main() { int x = 10; while (x –> 0) // x goes to 0 { printf(“%d “, x); … Read more

For some strange reason, sorting the data (before the timed region) miraculously makes the loop almost six times faster. #include <algorithm> #include <ctime> #include <iostream> int main() { // Generate data const unsigned arraySize = 32768; int data[arraySize]; for (unsigned c = … Read more
