while loop condition help

Create a variable, A =64 and use While-loop to do the following:

i. Calculate how many numbers between 0 and A are divisible by 3.

ii. Save all the numbers divisible by 3 in a vector called B.

iii. Change the value of A to 100 and repeat the previous 2 steps.

Thos is a homework that i have and i can't even begin to understand how to write the conditions for this loop

[darova]

Do you know how to declare variables?

Example

A = 64;

yes

i know the basics of matlab but i don't know how to solve this question

[darova]

What about this?

x/3

[Buti Al Falasi]

i know that ./ is for division but how do i write the condition for this .

though to be fair expect me to know nothing since i didn't use matlab for more than a week

[darova]

mod function can say if number has remainder of division

if mod(x,3) == 0
    disp('number is divisible by 3')
end

while loop using example

i = 1;
n = 10;
while i <= n
    i = i + 1;
    mod(i,3)
end

im doing a uni course for this and all they do is send a docement with instructions like do chapter 1 to 5 on matlab onramp then solve the homework so im really lost.

[Buti Al Falasi]

so thanks for the help

[darova]

if you spend a bit of time on this you can handle it
