+Increment and Decrement Operators (``++``, ``--``)
+==================================================
+
+These operators increment (add one to) or decrement (subtract one
+from) a variable.  If they come before the variable, they return its
+new value; otherwise, they return its old value.
+
+Some quick examples::
+
+    x++;  // adds one to x, and returns the old value of x
+    ++x;  // adds one to x, and returns the new value of x
+
+    x--;   // decrement x by one and returns the old value of x
+    --x;   // decrement x by one and returns the new value of x
+
+A more extended example::
+
+    x = 2;
+    y = ++x;      // x now contains 3, y contains 3
+    y = x--;      // x contains 2 again, y still contains 3
+
+.. warning:: Be careful!  You cannot put a space in between the two
+    ``+`` or ``-`` signs.  This example is broken::
+
+        // this line won't compile (notice the extra space):
+        int y = x+ +;
