C++ 指针

申明指针，并分配内存：typeName *pointName = new typeName;

int *int_ptr = new int;

释放：delete int_ptr;

int *ints_ptr = new int[10];

释放：delete  [] ints_ptr;

1     int *intPtr = new int[10];

2     cout<<intPtr<<endl;

3     for(int i=0;i<10;i++)

4     {

5         intPtr[i] =i*i*i; 

6         cout<<&intPtr[i]<<":"<<intPtr[i]<<endl;

7     }

8     delete [] intPtr;

9     cout<<intPtr<<endl;
