Im getting an error in my code saying,

pokemon2.cpp:43:12: warning: generalized initializer lists are a C++11 extension

[-Wc++11-extensions] return {movename, 0, damagevalue, 0, 0, 0, 0};

and also

"pokemon2.cpp:48:23: error: expected ';' after return statement return new Pokedex {NULL, NULL};"

here's my code. Not sure why. Can someone fix? (using GCC on Mac)
