This problem will test your variable handling skills.

(a) Write a function called hiddenSum that takes two inputs and returns the sum of the two inputs. Turn in a printout of the function.

(b) Write a script M-file called testHiddenSum.m that defines two variables x and y Assign some values to these variables. Call the function hiddenSum from within this script M-file and store the result in a local variable, z. Run the script M-file and turn in a printout with the value of z.

(c) Modify the function hiddenSum such that now it DOES NOT HAVE any output arguments. Now modify your script M-file such that it calls hiddenSum using x and y as inputs and assigns the result to the variable z. You will need to further modify your function file. Submit a printout of the new function and script files and command prompt results from running your script M-file.

(d) Now modify your function hiddenSum such that it DOES NOT HAVE any input OR output arguments. Modify your script M-file such that it calls hiddenSum using x and y as inputs, and stores the result in the variable z. You will need to further modify your function file. Submit a printout of the new function and script files, and the command prompt results from running your script M-file.
