hello ive started to use for and while loops in class to get a random number of loops asking for my input in a number then we need to add those numbers up to get a product ive done it with a for loop to get a sum of all numbers but i am stuck on the while loop and help would be apperciated her is the question; any help would be apperciated!

Hey @Alex Perez,
I see you want help in executing a while loop random number of times. Below is an example of how a random number can be generated in a specified range.
r = randi([3 5])
The above code generates a random integer in the range of 3 and 5 inclusive. You can use this “r” to control the number of iterations of while loop by using a counter variable. The below code snippet demonstrates how to do the same:
cnt = 0
while cnt < r
%perform operations - like taking input and computing running product
cnt=cnt+1
end
For more details, please refer to the following MathWorks documentations:
randi - https://www.mathworks.com/help/matlab/ref/randi.html
while - https://www.mathworks.com/help/matlab/ref/while.html
Hope this helps!
