Popular Myths about C++, Part 1

Try it with optimizations on:

gcc -std=c99 -O3 -Wall -Wextra test.c -o test

g++ -std=c++11 -O3 -Wall -Wextra test.cpp -o test

In my experience, C++ compilers are great at eliding temporaries and various constructor calls (and related memory allocations), but only if optimizations are turned on.

Thanks. It was worth a shot. Which version of GCC are we talking about?
