 The following code creates a lookup table for the day of the year, assuming 365 days per year. However, this doesn't work if the year is a leap year:
 
 ```cpp
-
-#include <vector> 
-
-void foo(int year) 
-{ 
-    const std::vector<int> items(365);  // C6393 
-    // Initialize items and use it... 
+#include <vector>
+
+void foo(int year)
+{
+    const std::vector<int> items(365);   // C6393
+    // Initialize items and use it...
 }
 ```
 
 To fix the problem, adjust the size of the lookup table as the table is created according to the result of appropriate leap year check:
 
 ```cpp
-#include <vector> 
-  
-void foo(int year) 
-{ 
-    bool isLeapYear = year % 4 == 0 && (year % 100 != 0 || year % 400 == 0); 
-    const std::vector<int> items(isLeapYear ? 366 : 365); 
-    // Initialize items and use it... 
+#include <vector>

+    // Initialize items and use it...
 }
