<p>What is forward reference in C with respect to pointers?</p>

<p>Can I get an example?</p>

See this page on
forward references
.  I don't see how forward referencing would be different with pointers and with other PoD types.
Note that you can forward declare types, and declare variables which are pointers to that type:
```
```
struct MyStruct;
struct MyStruct *ptr;
struct MyStruct var;  // ILLEGAL
ptr->member;  // ILLEGAL

struct MyStruct {
    // ...
};

// Or:

typedef struct MyStruct MyStruct;
MyStruct *ptr;
MyStruct var;  // ILLEGAL
ptr->member;  // ILLEGAL

struct MyStruct {
    // ...
};
```
```
I think this is what you're asking for when dealing with pointers and forward declaration.
