c++ - auto in c++11 is static typing or dynamic typing -

-

is auto command in c++11 static binding(typing) or dynamic binding?

i.e. if have code

auto x = 5;

will compiler decide "x" int, or descovered on runtime?

also, type of x in following code?

auto x = 5, y = 4.5

this called type inference. typing still static, leave compiler figure out type of expression is.

specifically auto x = 5;, @ compiler time, is translated int x = 5;. reason have provide unambiguous expression @ initialization. example auto x; wouldn't work.
