Question$-5($Using Structs$)$:

Structs are useful in many situations when dealing with diverse data. For example, get the contents of your

current directory by typing $a=$dir;

a$.,a$ is a struct array. What is its size? What are the names of the fields in $a?$

b$.$ Write a loop to go through all the elements of a$,$ and if the element is not a directory, display the

following sentence 'File filename contains $x$ bytes', where filename is the name of the file and $x$ is

the number of bytes.

c$.$ Write a function called displayDir.m$,$ which will display the sizes of the files in the current

directory when run, as below. Your output may have different filenames.
