iOS Objective-C Basics Scope and Loops Review Scope and Loops

Can't find my syntax error in this for loop.

The directions for this exercise are: 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 value to mathTotal. When the loop has finished running, set 'isComplete' to true. (HINT: the last value used INSIDE the loop should be 25)

I'm having a hard time spotting what is wrong with my syntax and what I need to correct. Should I be adding an if statement to ask something like: if mathTotal is equal to 25 then isComplete = YES?

variable_assignment.mm 
int mathTotal;
bool isComplete;

for (mathTotal = 5; mathTotal < 25; mathTotal++)
{
    isComplete = YES;
}

The key here is this sentence: "In each iteration, add the incrementing value to mathTotal." Basically, you don't want to use mathTotal as the counter in the for loop. Instead, do something like this:

for (int i = 5; i <= 25; i++)

Then you can use i to add to mathTotal inside the loop.

Hope this helps!

Thank you! It worked after I added the i into mathTotal inside the loop, but only after I added the equal sign to the less than symbol. It did say that it needed to end with 25, so I suppose I should have read that a bit more closely.

Thanks again.
