Write a script that asks the user to enter positive real numbers until their product becomes is greater than 500. The program should check if a negative number is entered, give a warning and then ask for another number. When a value of 500 is exceeded, the program should display the product of the numbers, state how many numbers were entered, and list the numbers. Use fprintf commands to display results and make the output look tidy.
I HAVE;
i=0; pro=1; while pro<500 n=input('enter a positive real number; '); while n<=0 disp('the number entered is not a positive real number'); n=input('enter a positive real number; '); end pro=pro*n; i=i+1; end disp(n) disp(pro); disp(i);

Dear Merapelo, your code is working perfectly. I just made a few modifications to make output look better:
i = 0;
pro = 1;
while pro < 500
n = input('enter a positive real number: ');
while n <= 0
warning('the number entered is not a positive real number');
n = input('enter a positive real number: ');
end
pro = pro * n;
i = i + 1;
end
fprintf('Product of entered positive numbers is: %d\nThe total number of values input were: %d\n', pro, i);
Good luck!

try it now:
i = 0;
pro = 1;
count = 1;
while pro < 500
n = input('enter a positive real number: ');
Values(count) = n;
count = count + 1;
while n <= 0
warning('the number entered is not a positive real number');
n = input('enter a positive real number: ');
Values(count) = n;
count = count + 1;
end
pro = pro * n;
i = i + 1;
end
fprintf('Product of entered positive numbers is: %d\nThe total number of values input were: %d\n', pro, i);
fprintf('Input values are:\n')
fprintf('\t%d\n', Values)
