syntax error C2061 using structs

Question

Got a bit confused about this error I'm getting ...

So, in this code snippet, I have 2 structs :

typedef struct 
{
    char  *cMake;   
    model *testModel;
} make;

typedef struct 
{
    char * cModel;    
} model;

Now, if I compile, I receive the following errors :

Error   1   error C2061: syntax error : identifier 'model'  
Error   2   error C2059: syntax error : '}' 

If I comment the model *testModel line, it compiles fine ... Any ideeas ? Thank you !

Answer 1

Declare model type before make :

typedef struct 
{
    char * cModel;    
} model;

typedef struct 
{
    char  *cMake;   
    model *testModel;
} make;

Generally an identifier name cannot be used before it has been fully declared.

Answer 2

order!

typedef struct 
{
    char * cModel;    
} model;

typedef struct 
{
    char  *cMake;   
    model *testModel;
} make;

your compiler doesn't know model when you use it, because it's defined later in the code.

Answer 3

You should declare model before tring to use it. The simplest way to do that in this case is to simply swap the two definitions around.

You could also forward declare model and leave the order the same but that's unnecessary here.

Answer 4

If you define model first, it works well.

   typedef struct
{
    char * cModel;
} model;

typedef struct
{
    char  *cMake;
    model *testModel;
} make;
