***How Can I Loop Interval Number Of Times ***

[shycas2008]

Team, I block commented at the bottom kind of what I need to see.
Here's where I am lost - I know how to do a do, while and an if loop.
But I'm confused on how to the loop number of interval times.
Any Idea?
I will obviously input multiple variables and append all this into a CSV.
This chunk of code I'm having an issue with.

 #include <iostream>
using namespace std;

int main()
{
int start_time_hh;
int start_time_mm;
int start_time_ss;
int start_month;
int start_day;
int start_year;
int dd_interval;

cout << "What Is The Date? - In MM/DD/YY Format:" << "\n";
char sep;
cin  >> start_month >> sep >> start_day >> sep >> start_year;
cout << "How Many Days Would You Like This To Occur? - XXX Format:" << "\n";
cin  >> dd_interval;
cout << "What Is The Time Of This Event? - In HH:MM:SS Format:" << endl;
cin  >> start_time_hh >> sep >> start_time_mm >> sep >> start_time_ss;

/*How Would I Loop (++start_day) by (dd_interval) amount of times - and output the result?

Example - 

12/15/17,09:00:00

dd_interval = 12 (User Input)

output desired = 

12/15/17,09:00:00
12/16/17,09:00:00
12/17/17,09:00:00
12/18/17,09:00:00
12/19/17,09:00:00
12/20/17,09:00:00
12/21/17,09:00:00
12/22/17,09:00:00
12/23/17,09:00:00
12/24/17,09:00:00
12/25/17,09:00:00
12/26/17,09:00:00
12/27/17,09:00:00

From the start time, end time and periodicity you'll know how many times the loop needs to run and with that information you can use std::this_thread::sleep_for()
http://www.cplusplus.com/reference/thread/this_thread/sleep_for/

[shycas2008]

I will jump over to that topic and have a look - is there a way you could display it for a dummy like me? If you have time that is.

[gunnerfunner]

here is a stylized outline with some comments, see if this on the lines of what you might need:

#include <iostream>
#include <chrono>     // std::chrono::milliseconds
#include <thread>   //std::this_thread::sleep_for

int main()
{
    std::this_thread::sleep_for (std::chrono::seconds(5));
    //the initial sleep_for period would be determined by the difference b/w current time and the future start time

    for (size_t i = 0; i < 10; ++i)
    //the number of times to loop would depend on the difference b/w future start and end times and the periodicity
    {
        std::cout << "hello world\n";
        std::this_thread::sleep_for (std::chrono::seconds(1));
    }
}

Hi, shycas2008,
I’m likely to be totally misunderstanding you question, but... Are you just asking for a strategy to increment the day of a date, keeping into account months, years, leap years...?
If so, please have a look to the following example.
It’s far from being optimized and you can easily find better ones googling around, but it’s based on your code.
If I got the wrong end of the stick, just ignore my post :-)
Please, consider the idea of writing your own class to manage these kind of problems, because a date can definitely being considered a different type.
Also: if you need to rely on your solution to a professional level, you should consider take advantage of the ready made functions in <ctime>.
