C++学习：new运算符使用

#include<iostream>
using namespace std;

int * test01() //堆区开辟整型数据空间
{
	int* p = new int(5);
	return p; //在main函数中进行了释放
}

void test02() //堆区开辟数组空间
{
	int *arr=new int[10];
	for (int i = 0; i < 10; i++)
	{
		arr[i] = i;
	}
	for (int i = 0; i < 10; i++)
	{
		cout << arr[i] << endl;
	}
	delete[] arr;
}
int main()
{
	//int* p1 = test01();
	//cout << *p1 << endl;
	//delete p1; 
	test02();
	system("pause");
	return 0;
}
