Is there an equivalent of type var in C ++?

Question

So, I know that C ++ is strongly typed, and it was just interesting if there was any library (or any thing for this fact) that would allow you to create a variable that does not have an initial concrete type like var in Python .

Answer 1

Take a look at boost::anyand boost::variant.

Answer 2

Two main things come to mind:

• BOOST_AUTO
• Type C ++ 0x inference

Answer 3

++ 11 auto, , . , :

auto index = 1; // index is inferred to be int
auto c = 'a' // c is inferred to be a char
