+// Line 3 is updating the value of the count variable. The = operator is an assignment operator, which assigns the value on the right (count + 1) to the variable on the left (count). In this case, it takes the current value of count (which is 0), adds 1 to it, and then assigns the result (1) back to count. So after this line executes, count will have a new value of 1.
