## 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
```
