返回数组指针的函数

#include <iostream>
using namespace std;
double* aaa()
{
    double tmp[3] = { 1.01,2.02,3.03 };
    double* tmp1 = new double[3];
    for (size_t i = 0; i < 3; i++) tmp1[i] = tmp[i];
    return tmp1;
}


int main()
{
    double* a = new double[3];
    a = aaa();
    for (size_t i = 0; i < 3; i++)
    {
        cout << *(a + i) << endl;
    }
    delete[]a;
    system("pause");
}

运行结果：

1.01
2.02
3.03
