new的用法复习

#include <iostream>
using namespace std;
int* func()
{
    int* p = new int(10);
    return p;
}
void test01()
{
    int* p = func();
    cout << "返回：" << *p << endl;
    //在堆区开辟数组
    int* arr = new int[10];
    for (int i = 0; i < 10; i++)
    {
        arr[i] = i;
    }
    for (int j = 0; j < 10; j++)
    {
        cout << arr[j] << endl;
    }

}
int main()
{
    test01();
    return 0;
}
