结构构件中未找到

Question

我有以下结构：

typedef struct vertex_tag{ 
    int visited = 0; 
    int weight = FLT_MAX; 
    int prev; 
}vertex_t; 

它具有三个部件，如上所述。

我malloc的顶点是这样的：

vertex_t * vertex[G->vertices]; 
    for(i=0; i < G->vertices; i++) 
    { 
     vertex[i] = (vertex_t*)malloc(sizeof(vertex_t)); 
    } 

所以我创建一个从结构的矩阵。然后我打电话给他们在整个我这样创建的函数：

vertex[i]->visited 
vertex[i]->weight 
vertex[i]->prev 

我不断收到以下错误：

error: ‘vertex_t’ has no member named ‘visited’ 
error: ‘vertex_t’ has no member named ‘weight’ 
error: ‘vertex_t’ has no member named ‘prev’ 

谁能帮我明白为什么我不能这样做呢？

Answer 1

Okay so I can do it after the for loop in which I malloced it?

你会做它在循环更好。

vertex_t *vertex[G->vertices]; 
    for (i = 0; i < G->vertices; i++) 
    { 
     vertex[i] = malloc(sizeof(vertex_t)); 
     vertex[i]->visited = 0; 
     vertex[i]->weight = FLT_MAX; 
    } 

或根据泽塔的建议：

vertex_t vertex[G->vertices]; 
    for (i = 0; i < G->vertices; i++) 
    { 
     vertex[i].visited = 0; 
     vertex[i].weight = FLT_MAX; 
    }
