Creating A For Loop

When I try to input the for loop, I keep getting a compiler error message:

expected expression for (int i=5, i<=25, i++)

I'm not sure what to do next?

variable_assignment.mm 
bool isComplete;
int mathTotal = 0;

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

Hi Janson,

The loop is correct although you have a small syntax error, a for loop should look like this:

for (int k = 1; k < 99; k++) {
       // do something
}

Hint: Notice the semicolon.

Hope this helps!
