c++ - Use static_cast on non-pointer POD instead of c style cast -

this question has answer here: why use static_cast<int>(x) instead of (int)x? 9 answers is there reason using static_cast on non pointer pod data types, int, float, double? float v = 100; int x = (int) v vs int x = static_cast<int>v is there reason/advantage on using that, saw several answers covers pointers, plain pod data not find explicit answers non-pointers. the best reason i've heard because can grep static_cast , know find casts whereas (int) less specific what's going on in expression. also, c-style casts can remove or add const or volatile , change types without warnings. if try static_cast const pointer/reference type non- const pointer/reference type, compile error.
