 ## Remarks
 
-The `#` sign of a preprocessor directive must be the first character on a line that is not white space.
+The `#` sign of a [preprocessor directive](../../preprocessor/preprocessor-directives.md) must be the first character on a line that is not white space. Ensure that the previous line doesn't contain a trailing escape.
 
 ## Example
 
 The following example generates C2014:
 
 ```cpp
 // C2014.cpp
-int k; #include <stdio.h>   // C2014
-```
+// compile with: /c
 
-Possible resolution:
+int a; #define A   // C2014
 
-```cpp
-// C2014b.cpp
-// compile with: /c
-int k;
-#include <stdio.h>
+int b;\
+#define B   // C2014
+
+int c;
+#define C   // OK
 ```
