Can't complete this "for" loop

Not sure what I'm doing wrong here? I know I'm missing something, just not sure what....

variable_assignment.mm 
int mathTotal;

bool isComplete;

for (int mathTotal = 5; mathTotal++; mathTotal == 25;) {
    iscomplete = true;
}

There's a few things. The isComplete value should be set to true only after the loop has completed running. The way you have it it keeps setting it to true with every iteration. Secondly your increment operator and the number of times you're running through the loop are in the wrong places. And, you're going to need a separate variable to keep track of the number of times you're going through the loop. Take a look at how I solved it and see if it makes sense. 

bool isComplete;
int mathTotal;

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

isComplete = true;
