In this program, we are going to learn adding seconds to the time.

Consider the program:

#include <iostream>
using namespace std;

void addSecond(int *hh, int *mm,int *ss)
{
	if( *ss == 59 )
	{
		if( *mm == 59 )
		{
			cout<<endl<<"hh: "<<*hh<<" mm: "<<*mm<<" ss:"<<*ss<<endl;
			
			if(*hh == 23)
				*hh=0;
			else
				(*hh)++;
				
			*mm=0;
			*ss=0;
		}
		else
		{
			(*mm)++;
			*ss=0;
		}
	}
	else
	{
		(*ss)++;
	}
}

int main()
{
	int hh=23,mm=59,ss=59;
	
	cout<<"Time before adding second(s): "<<hh<<":"<<mm<<":"<<ss<<endl;
	addSecond(&hh, &mm, &ss);
	cout<<"Time After adding second(s) : "<<hh<<":"<<mm<<":"<<ss<<endl;
	
	
	return 0;
}

Output

Time before adding second(s): 23:59:59

hh: 23 mm: 59 ss:59 
Time After adding second(s) : 0:0:0

In above example, we have added one second to 23:59:59 in 24 hours clock. Thus, the output is 0:0:0, it is in next day.
