i have a problem with this syntax. I use for loop in this challenge i think its right but i can't write the correct synt

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).

can you help me with this ? I use For Loop is it correct ?

variable_assignment.mm 
int mathTotal;
bool isComplete;

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

Hey Qahtan,

You're on the right track, it just needs a couple things. First off, the isComplete = true needs to be located outside of the loop. With it inside, it will evaluate to true after the first loop iteration.

Second, the challenge wants you to add the iteration values to the mathTotal variable after each run. So 6 will be added to five ... then 7 will be added to 11 (5 +6), etc. This needs to be inside the loop.

So, just a couple minor adjustments and you're good to go. :dizzy:

int mathTotal;
bool isComplete;


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

isComplete = true;
