Question

Take the code below, and split it up into several files. Make a C (.c) file, containing at least one function. Then make a header (.h) file for it. Finally, make another program with a "main" function, to call the function.

int main()

{ int timehours, timeminutes,totaltime, flightarrival,

flightdeparture;

printf("Enter a 24-hour time: ");

scanf("%d:%d",& timehours, & timeminutes);

totaltime=timehours * 60 + timeminutes;

if(totaltime<=480)/*8:00 a.m.*/

{flightdeparture=480;

flightarrival=616;

}

else if(totaltime<=583)/*9:43 a.m.*/

{flightdeparture=(totaltime-480)<=(583-totaltime)?480:583;

flightarrival=(totaltime-480)<=(583-totaltime)?616:712;

}

else if(totaltime<=679)/*11:19 a.m.*/

{ flightdeparture =(totaltime - 583)<=(679-totaltime)?583:679;

flightarrival =(totaltime-583)<=(679-totaltime)?712:811;

}

else if(totaltime<=767)/*12:47 p.m.*/

{ flightdeparture=(totaltime -679)<=(767-totaltime)?679:767;

flightarrival=(totaltime-679)<=(767-totaltime)?811:900;

}

else if (totaltime<=840)/*2:00 p.m.*/

{ flightdeparture=(totaltime-767)<=(840-totaltime)?767:840;

flightarrival=(totaltime-767)<=(840-totaltime)?900:968;

}

else if(totaltime<=945)/*3:45p.m.*/

{flightdeparture=(totaltime-840)<=(945-totaltime)?840:945;

flightarrival=(totaltime-840)<=(945-totaltime)?968:1075;

}

else if(totaltime<=1140)/*7:00 p.m.*/

{flightdeparture=(totaltime-945)<=(1140-totaltime)?945:1140;

flightarrival=(totaltime-945)<=(1140-totaltime)?1075:1280;

}

else /*9:45 p.m.*/

{

flightdeparture=(totaltime-1140)<=(1305-totaltime)?1140:1305;

flightarrival=(totaltime-1140)<=(1305-totaltime)?1280:1438;

}

timehours=(flightdeparture/60);

timeminutes=(flightdeparture-(timehours*60));

if(timehours>=12)

{

if(timehours!=12)

timehours=timehours-12;

printf("Closest departure time is %d:%.2d p.m,",

timehours,timeminutes);

}

else

printf("Closet departure time is %d:%.2d a.m,",

timehours,timeminutes);

timehours=(flightarrival/60);

timeminutes=(flightarrival-(timehours*60));

if(timehours>=13)

{

if(timehours !=12)

timehours=timehours-12;

printf("arriving at %d:%.2d p.m.\n", timehours,timeminutes);

}

else

printf("arriving at %d:%.2d a.m.\n", timehours,timeminutes);

return 0;

}
