Description

The position of a robotic arm is determined by an angle that can only take values between $-60$

degrees and $+120$ degrees $($included$).$ In this homework, you will create a C$++$ class Angle that

represents the angle of the robotic arm. The implementation should enforce the limits on the

range of allowed values. The angle can only take integer values. Any attempt to change the angle

beyond a limit should result in the angle value being that limit$.$ For example, any attempt to

change the angle to a value smaller than $-60$ should result in the angle value being $-60.$

The class Angle includes a public member function change$($int dt$)$ and a private member

function set$($int t$).$ The change function uses the set function to change the angle by the

amount dt$.$ The argument dt may be positive or negative. The initial angle value at the time

the robotic arm is powered up is $30$ degrees. The Angle object should set its angle value to be

$30$ when the object is created. See the file Angle.h for details and other member functions.

The Angle class is used by a program robot.cpp that is provided. The output of the program

robot must reproduce exactly the contents of the file robot.out.

The files Angle.h and robot.cpp are provided and must not be modified. You must create a

file Angle.cpp containing the implementation of your Angle class. It must be possible to

compile the program robot.cpp to generate an executable named robot using the command:

make

without generating any warning message. The Angle class that you provide will also be

compiled and linked with another program that uses the Angle member functions when grading

the assignment. You must create a Makefile that contains a target robot and a target

clean. The target robot should appear first and will be used to build the executable robot.

The target clean will be used to remove all object files and executables. The Makefile

should include the necessary definition to compile C$++$ files using g$++$ with the $$Wall option.

Submission

Create a tar file named hw$1$p$1.$tar containing the files Angle.cpp and Makefile only.

Do not compress the tar file. Include your name and Student ID in a comment at the top of each

file. Submit your tar file hw$1$p$1.$tar using Gradescope.
