有这样的代码:

#include <iostream>

int main(){
  unsigned int* wsk2 = new unsigned int(5);
  std::cout << "wsk2: " << wsk2 << " " << *wsk2 << std::endl;
  delete wsk2;
  wsk2 = new unsigned int;
  std::cout << "wsk2: " << wsk2 << " " << *wsk2 << std::endl;
  return 0;
}

结果:

wsk2: 0x928e008 5
wsk2: 0x928e008 0

我读过new没有用零初始化内存.但似乎它确实如此.它是如何工作的？
