我如何在指針數組中分配指針值

Question

我有這個錯誤：

ID3.c:71:53：錯誤：從類型“t_object *”{又名“結構 object *”} 分配給類型“t_object”{又名“結構對象”}時類型不兼容 *'} 71 | (objects->v[sizeof(void *) * i]) = t_object_ctor(); | ^~~~~~~~~~~~~

我試過這個：

&(objects->v[sizeof(void *) * i]) = t_object_ctor();

並嘗試了這個

*(objects->v[sizeof(void *) * i]) = t_object_ctor();

這給出了同樣的錯誤

*((objects->v)+[sizeof(void *) * i]) = t_object_ctor();

這是錯誤所在的函數： t_objects *t_objects_ctor(){ t_objects *objects =malloc(sizeof(t_objects));

    objects->size = 0;
    objects->y = 0;
    objects->x = 0;
    objects->x_size= malloc(sizeof(size_t) * RESONABLENUMBER);
    objects->v= malloc(sizeof(void *) * RESONABLENUMBER);
    for (int i = 0; i < RESONABLENUMBER; ++i) {
        *((objects->v) + sizeof(void *) * i) = t_object_ctor();
    }
    objects->b_size = 0;
    objects->b = NULL;
    
    return objects;
}

這是 function 即時分配指針來自：

t_object *t_object_ctor(){
    t_object *object =malloc(sizeof(t_object));
    
    object->s = 0;
    object->x = NULL;
    object->y = 0;
    
    return object;
    
}

嘗試這個：

((t_object **)objects->v)[i] = t_object_ctor();

完整代碼如下：

#include <stdio.h>
#include <stdlib.h>
#include <string.h>

#define RESONABLENUMBER 16
typedef struct t_objects {
    int size;
    int x, y;
    void *x_size;
    void *v;
    int b_size;
    char *b;
} t_objects;

typedef struct t_object {
    int s;
    void *x;
    int y;
} t_object;

t_object *t_object_ctor()
{
    t_object *object = malloc(sizeof(t_object));

    object->s = 0;
    object->x = NULL;
    object->y = 0;

    return object;
}

t_objects *t_objects_ctor()
{
    t_objects *objects = malloc(sizeof(t_objects));

    objects->size = 0;
    objects->y = 0;
    objects->x = 0;
    objects->x_size = malloc(sizeof(size_t) * RESONABLENUMBER);
    objects->v = malloc(sizeof(void *) * RESONABLENUMBER);
    for (int i = 0; i < RESONABLENUMBER; ++i) {
        ((t_object **)objects->v)[i] = t_object_ctor();
    }
    objects->b_size = 0;
    objects->b = NULL;

    return objects;
}

int main()
{
    t_objects_ctor();
    return 0;
}
