$24\mathrm{.}23$ LAB: Time difference

The template code defines a Time class. Given a main function that reads two Times and computes the difference between the two, complete the following two functions:

void ReadTime$()$

Reads input for hours, minutes, and seconds, respectively.

void TimeDifference$($Time end, Time start$)$

Compute the amount of time elapsed from start to end. Assume start is always before end.

Adjust for negative minutes and seconds.

The main function calls a Time's ReadTime$()$ to read input from a user and uses the input to populate the Time's member variables. PrintTime$()$ is provided to output Time in $24$ hour format $($hh:mm:ss$).$
