C++ | Q : cygwin exception when executing the executable |

Question

下面我写了一个简单的例子来演示我遇到的问题。执行代码后，我得到一个 cygwin 异常 7200。我环顾四周并尝试了一些事情，但没有解决。有人可以解释为什么我得到它，我该如何解决？感谢您抽出宝贵时间，在此先致谢!

代码

#include <string>
#include <vector>

// string 
using std::string;

// vector
using std::vector;

class Person{
private:
  string name;
  int age;
public:
  Person(string& name, int& age);
};

Person::Person(string& name, int& age): name(name), age(age){}

int main(){
  vector<Person> people;

  string* names = new string[3];

  names[0] = "bob";
  names[1] = "alice";
  names[2] = "hank";

  int* ages = new int[3];

  ages[0] = 10;
  ages[1] = 20;
  ages[2] = 30;

  for(unsigned int i = 0; i < 3; ++i){
    Person person(names[i], ages[i]);
    people.push_back(person);
  }

  delete names;
  delete ages;

  return 0;
}

错误

0 [main] a 7200 cygwin_exception::open_stackdumpfile: Dumping stack trace to a.exe.stackdump

P.S - 我对 C++ 比较陌生。

您需要使用 delete[] 而不是 delete 来删除数组。

delete[] names;
delete[] ages;
