Basic While Loop (divide random scalar by 7 until less than 1) Question

Requirements (3/4 finished except last one):

• Is first output whatsLeft correct for input number of 256?
• Is second output divisionCount correct for input number of 256?
• Are both outputs correct for an input that is a random number in the thousands
• Does solution use a while loop?

Here's is my code so far:

function [whatsLeft, divisionCount] = divideBySeven(number)
%Enter the code for your function here.   
if (number > 0)
        temp = number;
        counter = 0;
        while temp >= 1
            temp = temp/7;
            counter = counter + 1;
        end
        whatsLeft = temp;
        divisionCount = uint8(counter);  
    end
end

Hi Batuhan,

As per my understanding, you are trying to perform “divide by seven” operation using “while” loop. You have a code containing both “if” and “while” loops in it and I assume that the code needs “while” loop only.

I have updated the MATLAB code, for your reference.

function [whatsLeft, divisionCount] = divideBySeven(number) 
counter=0; 
%Enter the code for your function here.    
while(number>=1) 
    number=number/7; 
    counter=counter+1; 
end 
whatsLeft=number; 
divisionCount=counter; 
end 

Hope this answer helps you.

Thanks,

Bhanu Prakash.
