# hooks-guard-in-for
|
|
|
|
A guard is a marker that must be placed in your code at the top of each loop. Consider the following for-loop in C:
|
|
|
|
```c
|
|
#define GUARD(maxiter) _g(__LINE__, (maxiter)+1)
|
|
|
|
for (int i = 0; GUARD(3), i < 3; ++i)
|
|
```
|
|
|
|
<BR/>
|
|
This is the only way to satisfy the guard rule when using a for-loop in C.
