Optimizing C++/Writing efficient code/Memory access. Even with g++ -O0 (yes, -O0 !), this happens. It is always harder to debug optimised programs, but there are always ways. Can someone show me a simple tail-recursive function in C++? GCC can use that data to optimize conditionals to perform as quickly as possible in the expected case, with slightly slower execution in the unexpected case. In the world of C++ programming, all other things being equal, programs that are smaller and faster are better. Remember Ahmdal's Law: Speedup = timeold timenew. From Wikibooks, open Data caches optimize memory access in increasing sequential order. When compared to C, C++ has some features that worsen efficiency if used inappropriately.
