Question from the Language C - Fundamentals test

What is the value of the variable "year" at the loop output?

int main()
{
        double height = 1.05;
        int year= 0;
        do
        {
            printf("you're too small for this ride, come back next year\n");
            year++;
            height+= 0.20;
        } while (height < 1.25);
        printf("%d",year);
        return 0;
   }
