CODE IN MATLAB

Complete the following prompts: Ask a user to input a number between 20 and 80. Validate the data and if it is outside the range have the user input another number. Repeat this until a valid number is input. a) b) Create a 5x5 array of random integer numbers. Use loops to display every element of the array in any order one element at a time c) Display every other number between 1 and 20 using only a single for loop and a single disp function (see below). You can only modify the expression and the variable. Everything else MUST remain the same, for (expression) disp (variable) The WILLIAM STATES LEE COLLEGE of ENGI end

Explanation / Answer

num = input("Enter a number between 20 and 80: ");

while num <20 || num >80
num = input(" Invalid Number. Enter a number between 20 and 80: ");
end

%{ SAMPLE OUTPUT

Enter a number between 20 and 80: 10

Invalid Number.
Enter a number between 20 and 80: 90

Invalid Number.
Enter a number between 20 and 80: 56

r = rand(5);

% LOOPS through rows
for i = 1:5
for j = 1:5 % loops through columns
fprintf("%d ",r(i, j))
end
fprintf(" ")
end
