 ===== A single statement occupying multiple lines =====
+A second use of indentation is to highlight a line of code which wraps past the maximum line limit.  This frequently occurs in parameter lists, output statements and variable declarations.    Indentation gives programmers a visual clue that the line has been wrapped.
+In a long parameter list, break the line at the beginning of a parameter declaration and align the next parameter declaration with the first declaration on the line above it.
+<code c++>
+void FloodFill(int & worldArray[MAX_ROWS][MAX_COLUMNS], int rowSize,
+               int colSize, int fillColor, int backgroundColor,
+               int currentRow, int current column);
+</code>
+When declaring multiple variables of a single type it is helpful to indent each new identifier, especially when variables are initialized in the same statement.
+<code c++>
+    int rowSize = 10,
+        colSize = 20,
+        fillColor = 4,
+        backgroundColor = 7;
