C++中基本数据类型的较特别形式的初始化

#include <iostream>


using namespace std;




template <typename T>


class Test




...{


private:




T type;




int *p;




public:




Test(void) : type(T()), p() // p(int*()) is not valid




...{




}


};






int main(void)




...{


char c = char();


short s = short();


int i = int();


long l = long();




// int *p = int*(); is invalid




int *p = int(); // valid




Test<int*> t;




// All the variants above are initialized as zero.




return 0;


}
