Create a for loop that will begin with a value of 5 and end with a value of 25. In each iteration, add the incrementing

int mathTotal; bool isComplete; for (mathTotal = 5; mathTotal <25; mathTotal++); while { mathTotal=25 }

isComplete=true;

variable_assignment.mm
int mathTotal;
bool isComplete;

for (mathTotal = 5; mathTotal <=25; mathTotal = mathTotal++)

  while {
mathTotal=25 
}

isComplete = true;

Have you tried making the changes I suggested? That would definitely be a first step towards resolving your compiler errors. If you're having trouble understanding the concepts, maybe giving the videos a second look would help clarify what you're not understanding.

If after doing those things, you're still having a hard time, I'll try to help you out more. It would be beneficial for you to get a better understanding of these concepts, as they are the building blocks with which you will be building your iOS apps in the future.

Give those a try and let me know if you still need more help!

There are a couple of syntax problems in your code. First, you don't need to say mathTotal = mathTotal++ at the end of your for statement. That last part just needs to increment the counter variable mathTotal. So mathTotal++ should be all that's needed.

Next, you have a while statement inside your for loop. That is definitely not needed.

Lastly, what you really should be doing is declaring a new variable to use as the loop counter in your for loop. Then, in the body of the loop, you would add that value to mathTotal. It would look something like this:

for (int i = 5; i <= 25; i++)
{
    mathTotal += i;
}

Hope this helps!
