$($a$)$ Sketch a flowchart $($Visio diagram$)$ for Matlab code that repeatedly prompts a user to enter

$(5$ marks$)$

a prime number until the user enters a prime number. Use a while loop and an if statement.

$($b$)$ Write a Matlab code snippet for the problem outlined in $($a$)$ above. Your code should output appropriate messages when the number entered is$,$ and is not, a prime number. Hint: Use a while loop and Matlab's input $(),$ disp $()/$ fprintf $()$ and

$(5$ marks$)$

isprime $()$ functions.

$($c$)$ Consider the arrays below containing the names of elements and their corresponding atomic weights:

element$=["$Hydrogen$"$ "Helium" "Lithium"$]$;

a$\_$weight $=[1\mathrm{.}007,4\mathrm{.}003,6\mathrm{.}941]$;

Using Matlab's fprintf$()$ function, write code that uses a for loop to print out the following:

The atomic weight of Hydrogen is $1\mathrm{.}007$amu

The atomic weight of Helium is $4\mathrm{.}003$amu

The atomic weight of Lithium is $6\mathrm{.}941$amu

$($d$)$ Write a piece of code that uses a nested for loop and an if statement to display the array elements whose value is less than $5.$

$E=\left[\begin{array}{ccc}2& 3& 7\\ 1& 3& 9\\ 10& 8& 3\end{array}\right]$
