e.g.:
Code:struct foo { int a, b, c; }; struct foo f = { .b = 1024, .c = 4096 };
...or was this just a gcc extension for c? I've looked through the options listing but didn't find an obvious switch for this - perhaps there's an undocumented one?
designated structure initialization not allowed in c++?

Code:#include <cmath> #include <complex> bool euler_flip(bool value) { return std::pow ( std::complex<float>(std::exp(1.0)), std::complex<float>(0, 1) * std::complex<float>(std::atan(1.0) *(1 << (value + 2))) ).real() < 0; }

C99 only I'm afraid.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
ah, I see. thank you.
