Is it possible to print a variable's type in standard C++?

Question

For example:

int a = 12;
cout << typeof(a) << endl;

Expected output:

int

Answer 1

Very ugly but does the trick if you only want compile time info (e.g. for debugging):

auto testVar = std::make_tuple(1, 1.0, "abc");
decltype(testVar)::foo= 1;

Returns:

Compilation finished with errors:
source.cpp: In function 'int main()':
source.cpp:5:19: error: 'foo' is not a member of 'std::tuple'
