MATLAB Exercise 1: Statements, Loops and Functions

Exercise 2

Write a function nexthour that receives one integer argument, which is an hour of the day, and returns the next hour. This assumes a 12-hour clock; so, for example, the next hour after 12 would be 1.

Requirements:

Function name: nexthour
Input: one integer argument (hour)
Output: next hour (12-hour clock)
Handle the wrap-around from 12 to 1

Here are two examples of calling this function:

>> fprintf('The next hour will be %d.\n',nexthour(3))

The next hour will be 4

>> fprintf('The next hour will be %d.\n',nexthour(12))

The next hour will be 1

Example Calls:

>> fprintf('The next hour will be %d.\n', nexthour(3))
The next hour will be 4.
>> fprintf('The next hour will be %d.\n', nexthour(12))
The next hour will be 1.
                

Function Template:

function next_h = nexthour(current_hour)
    % NEXTHOUR Returns the next hour on a 12-hour clock
    % Input: current_hour - integer from 1 to 12
    % Output: next_h - next hour (1-12)
