For loop question help in code challenge

The challenge is "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)"

And I can't figure out exactly what it's asking and how to set isComplete to true after the loop is finished.

variable_assignment.mm 
int mathTotal;
bool isComplete;

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

isComplete = true;

Inside your function you are not adding mathTotal to 'i'. You are assigning the value of i to mathTotal.

I changed it to this:

int mathTotal; bool isComplete;

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

isComplete = true;

but it's still not working, and I can't figure out if I'm doing the right thing in just writing in isComplete = true; to set it to true after it runs

You might try instantiating the two variables before the for loop. That might be it.
