C++程序未运行

我是C++的新手，今天我编写了以下程序：

#include <iostream>
using namespace std;
typedef struct item
{
int hour;
int minute;
int second;
void print()
{
cout << hour << ":" << minute << ":" << second << endl;
}
}time;
time nirmul_time(time a);
time* timing_array(int size);
void print_times(time* array, int size);
int main()
{
time* our_array;
int size;
cout << "Give me the size of the array: " << endl;
cin >> size;
our_array = timing_array(size);
print_times(our_array, size);
delete[]our_array;
}
time nirmul_time(time a)
{
a.minute = a.minute + (a.second / 60);
a.second = a.second % 60;
a.hour = a.hour + (a.minute / 60);
a.minute = a.minute % 60;
a.hour = a.hour % 24;
return a;
}
time* timing_array(int size)
{
int i = 0;
bool overflow = false;
time* array;
array = new time[size];
for (i; i < size; i++)
{
cout << "enter the hours: " << endl;
cin >> array[i].hour;
if (array[i].hour > 23)
overflow = true;
cout << "enter the minutes: " << endl;
cin >> array[i].minute;
if (array[i].minute > 59)
overflow = true;
cout << "enter the seconds: " << endl;
cin >> array[i].second;
if (array[i].second > 59)
overflow = true;
if (overflow)
{
nirmul_time(array[i]);
}
overflow = false;
}
return array;
}
void print_times(time* array, int size)
{
int i = 0;
for (i; i < size; i++)
{
array[i].print();
}
}

当我尝试通过ctrl+F9或ctrl+F5运行它时，程序没有运行，我得到以下错误：

此外，当我尝试通过调试器ctrl+F5运行时，我会收到一条错误消息：在此处输入图像描述

我试着重新打开这个项目，并在online shell中运行它，但仍然不起作用，有人能帮我检测问题吗？
