C Plus Plus to convert hours into weeks days and hours 
ALGORITHM : Hours Conversion
This algorithm is used to input hours and convert into weeks, days and hours.
 Start
 Input Hours
 Calculate Weeks = Hours / 168
 Calculate Hours = Hours Mod 168
 Calculate Days = Hours / 24
 Calculate Hours = Hours Mod 24
 Display "Weeks=", Weeks
 Display "Days=", Days
 Display "Hours =", Hours
 End
C++ Code: Program Hours Conversion into Weeks, Days and Hours.
/* This program is used to input hours from the user. Then this algorithm "Hours Conversion" will convert hours into weeks, days and hours.*/
#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
int h, w, d, hrs;
cout<<"Enter Hours=";
cin>>hrs;
h = hrs;
w = hrs / 168;
hrs = hrs % 168;
d = hrs / 24;
hrs = hrs % 24;
cout<<"Total Hours input = "<<h<<endl;
cout<<"Weeks ="<<w<<endl;
cout<<"Days ="<<d<<endl;
cout<<"Hours ="<<hrs;
getch();
}
OUTPUT of Sample Run of The Program Hours Conversion
Enter Hours= 200
Total Hours input =200
Weeks = 1
Days =1
Hours =8
Logic of The Program Hours Conversion
We know that:
1 day = 24 hours
so 1 week = 24 x 7 = 168 hours
Therefore we will divide total hours by 168 to get weeks.
weeks = 200 / 168 will give 1 week.
Now to calculate remaining hours we will get remainder of the division 200 % 168
This will give remaining hours = 32
To get days, we will divide remaining hours by 24
so 32 / 24 will give 1 day.
Now we will calculate remaining hours by remainder 32 % 24 that will give the result 8 hours.
So the output 1 week, 1 day and 8 hours.
