模板元编程如何在这里工作(static const int value = 1 + StarCounter<\U>::value;)打印出来3？
#include <iostream>
template <typename T>
struct StarCounter
{
static const int value = 0;
};
template <typename U>
struct StarCounter<U*>
{
static const int value = 1 + StarCounter<U>::value;
};
int main()
{
std::cout << StarCounter<int***>::value << std::endl;//How is it printing 3?
return 0;
}
