for loop exercise not working but my answer should be correct

Anybody get anything similar to this? it runs fine on xcode but fails on the test when submitted but does what it says on the tin :) ?

int mathTotal; bool isComplete; for (int i = 5; i <= 25; i++) { mathTotal++; if (mathTotal == 25) { isComplete = true; } } // done

variable_assignment.mm 
int mathTotal; //create an int called mathTotal
bool isComplete;  //create a bool called isComplete
for (int i = 5; i <= 25; i++) {
   mathTotal++;
   if (mathTotal == 25) {
     isComplete = true;
   }
} // done

Hi there

You're totalling the wrong value. You should add the incrementing value into mathTotal - that's not the same as increment mathTotal. The only incrementing value is the for loop counter variable. So, at each iteration, add i to mathTotal and set isComplete to true when i equals 25.

Steve.
