Help in code challenge!

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)

variable_assignment.mm 
    int mathTotal;
    bool isComplete;

Stephen, the loop counter needs to start at 5 and increase by 1 until it reaches 25. Each time through the loop add the value of the loop counter to mathTotal.

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

Note that x += n is shorthand for x = x + n
