Why would the following not work?
int main(){
vector<double> vd;
decltype(vd.value_type) otherDouble = 2.2;
}
Thanks.
int main(){
vector<double> vd;
decltype(vd.value_type) otherDouble = 2.2;
}
Thanks.

value_type is already a type, so applying decltype on it does not make
sense. I guess this is what you are after:
#include <vector>
int main(){
std::vector<double> vd;
decltype(vd)::value_type otherDouble = 2.2;
}
