- Soft tabs are to be used instead of hard tabs
- A space is to be inserted between a pointer and its object name upon
declaration or in function signatures. Example:

```C
int * a;

instead of
+
```C
int *a;
```

- Don't explicitly cast malloc, but do
+
```C
ptr = malloc(sizeof(*ptr) * len);

- When checking for invalid pointers use

```C
if (ptr == NULL)
