remove_extent Class
Makes element type from array type.
template<class Ty>
struct remove_extent;
Parameters
- Ty
The type to modify.
Remarks
An instance of the type modifier holds a modified-type that is Ty1 when Ty is of the form Ty1[N], otherwise Ty.
Example
// std_tr1__type_traits__remove_extent.cpp
// compile with: /EHsc
#include <type_traits>
#include <iostream>
int main()
{
std::cout << "remove_extent<int> == "
<< typeid(std::remove_extent<int>::type).name()
<< std::endl;
std::cout << "remove_extent<int[5]> == "
<< typeid(std::remove_extent<int[5]>::type).name()
<< std::endl;
std::cout << "remove_extent<int[5][10]> == "
<< typeid(std::remove_extent<int[5][10]>::type).name()
<< std::endl;
return (0);
}
remove_extent<int> == int remove_extent<int[5]> == int remove_extent<int[5][10]> == int [10]
