% Menu-driven program to convert a time from seconds

% to other units specified by the user

% Generate a random time in seconds

rantime = randi([1 10000]);

% Call a function to display a menu and get a choice

choice = timeoption;

% Choice 3 is to exit the program

while choice ~= 3

 switch choice

 case 1

 fprintf('%d seconds is %.1f minutes\n',...

 rantime, secsToMins(rantime));

 case 2

 fprintf('%d seconds is %.2f hours\n',...

 rantime, secsToHours(rantime));

 end

 % Generate a random time in seconds

 rantime = randi([1 10000]);

 % Display menu again and get user's choice

 choice = timeoption;

end

timeoption.m

function choice = timeoption

% Print the menu of options and error-check

% until the user pushes one of the buttons

% Format of call: timeoption or timeoption()

% Returns the integer value of the choice, 1-3

choice = menu('Choose a unit', 'Minutes', ...

 'Hours', 'Exit');

% If the user closes the menu box rather than 

% pushing one of the buttons, choice will be 0

while choice == 0

 disp('Error - please choose one of the options.')

 choice = menu('Choose a unit', 'Minutes', ...

 'Hours', 'Exit');

end

end

secsToMins.m

function mins = secsToMins(seconds)

% Converts a time from seconds to minutes

% Format secsToMins(seconds)

% Returns the time in minutes

mins = seconds / 60;

end

secsToHours.m

function hours = secsToHours(seconds)

% Converts a time from seconds to hours

% Format secsToHours(seconds)

% Returns the time in hours

hours = seconds / 3600;

end
