将结构复制到结构数组

Question

Hey guys I need some help. I'm trying to store a SCar struct into an array of Scar inside the SOwner structure, for each different SOwner, though I'm getting this error:

Incompatible types when assigning to type 'Scar' from type 'struct SCar *'

Here's some code :

typedef struct {
char name[40];
SCar cars [100];
} SOwner;

typedef struct {
char color[40];
char brand[12];
} SCar;

SOwner *ownerPTR;
SCar *carPtr

void function(){
for(i=0; i<10 ; i++){
    (ownerPtr)->cars[i] = (carPtr+i);   // Problem here <<<--
}

Is there any simple way to make this work out? Thanks

Answer 1

You must dereference the pointer on the right hand side to generate a value of type SCar .

Like so:

ownerPtr->cars[i] = carPtr[i];

or

ownerPtr->cars[i] = *(carPtr + i);

But the latter is just a more complicated way to write the former, so just use indexing.

Answer 2

you have to define an array of pointers

typedef struct {
    char name[40];
    SCar * cars [100];
} SOwner;
