Question

Time can be expressed in [hours, minutes, seconds]. Create a program in C++ that takes a current time and adds an elapsed time to compute the future time. NOTE: hours are expressed using the 24 hours clock. For example, if the current time is 17, 34, 56 and the elapsed time is 9, 48, 17 then the future time is 3, 23, 13.

You should have variables cth, ctm, cts, eth, etm, ets, fth, ftm, fts, representing the current/elapsed/future hours/minutes/seconds.

Answer 1

SourceCode:

#include <iostream>

using namespace std;

int main()
{
//Declaring the variables
int cth, ctm, cts, eth, etm, ets, fth, ftm, fts;

//Taking input form the user
cout << "Please enter values for hour,minutes and seconds for current time: " << endl;
cin>>cth;
cin>>ctm;
cin>>cts;

cout << "Please enter values for hour,minutes and seconds for elapsed time: " << endl;
cin>>eth;
cin>>etm;
cin>>ets;
//Computing the future seconds
fts = (cts + ets) % 60;
//Computing the future minutes
ftm = ((ctm + etm) + ((cts + ets) / 60)) % 60;
//Computing the future hours
fth = ((cth + eth)+(((ctm + etm) + ((cts + ets) / 60))/60)) % 24;
//Printing the output
cout<<"Future time in hour,minutes and seconds in respectively are: "<<fth<<","<<ftm<<","<<fts;

return 0;
}
