+// Line 3 is updating the value of the count variable. The = operator is an 
+// assignment operator, which assigns the value on the right side 
+// (count + 1) to the variable on the left side (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 line 3 executes, count will 
+// have a new value of 1.
