3. Write a function elapsed_time that takes as its arguments two time structures and returns a time structure that represents the elapsed time (in hours, minutes, and seconds) between the two times. So the call

elapsed_time (time1, time2)

where time1 represents 3:45:15 and time2 represents 9:44:03, should return a time structure that represents 5 hours, 58 minutes, and 48 seconds. Be careful with times that cross midnight

Pseudocode for the function

time elapse_time (time time1, time time2)

{

/ * hour * /

if (time2. hr > = time1. hr) then

elapse_time. hr = time2. hr - time1. hr;

else / * pass mid night * /

elapse_time. hr = 24 + time2. hr - time1. hr;

endif

/ * min * /

if (time2. min > = time1. min) then

elapse_time. min = time2. min - time1. min;

else

elapse_time. hr = elapse_time. hr - 1;

elapse_time. min = 60 + time2. min - time1. min;

endif

/ * sec * /

if (time2. sec > = time1. sec) then

elapse_time. sec = time2. sec - time1. sec;

else

elapse_time. min = elapse_time. min - 1;

elapse_time. sec = 60 + time2. sec - time1. sec;

endif

return elapse_time;

}
