Question

The script below calls a function nexthour that receives one integer argument, which is an hour of the day, and returns the next hour on a 12-hour clock, regardless of whether the inputted current hour is on a 12-hour or 24-hour clock.

     Hour=input(‘Enter the current hour: ’);
     Hour = floor(Hour);
     if Hour>=1 && Hour<=24

fprintf(‘The next hour will be %d.\n’, nexthour(Hour) ) else

        fprintf(‘Please enter a number from 1 to 24.’)
     end

Sample output from the program is provided below:

     Enter the current hour: 57
     Please enter a number from 1 to 24.

     Enter the current hour: 15
     The next hour will be 4.

     Enter the current hour: 12
     The next hour will be 1.

Write the function nexthour so that it produces the results shown above.
