6.CPP风格数组

 //数组初始化
 1 #include <iostream>
using namespace std;



void main()
{
    //C int a[5] = { 1,2,3,4,5 };
    //C++ int a[5]{ 1,2,3,4,5 };

    //C int *p = new int[5]{ 1,2,3,4,5 };    
    //C++ int *p2(new int[5] { 1, 2, 3, 4, 5 });


    cin.get();
}

• C++风格数组

  #include <iostream>
  #include <array>
  using namespace std;
  
  
  
  void main()
  {
      //一维数组
      //在栈上分配内存
      //前面是元素类型
      array<int, 10>myint = { 1,2,3,4,5,6,7,8,9,10 };//CPP分个
      /*for (auto i : myint)
      {
          cout << i << endl;
      }*/
  
      array <array<int, 10>, 3>myint2{ myint,myint,myint };
  
      for (auto i : myint2)
      {
          for (auto j : i)
          {
              cout << j << "  ";
          }
          cout << endl;
      }
      cin.get();
  }
