我在打印节点的id成员变量时得到了这段代码和一个奇怪的行为.

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

struct node
{
    int id;
    int visited;
//    struct node *neighbors_[];
};

struct graph
{
    struct node nodes[26];
    int adjMat[26][26];

};

struct stack_item
{
    struct node node;
    struct stack_item *next_;
};

struct myStack
{
    struct stack_item *anfang_;

};

void initGraph(struct graph *graph_);
void push(struct myStack *stack_, struct node node);

int main()
{

    struct graph graph;
    struct myStack stack;
    char ausgabe[26]="";

    initGraph(&graph);


    //READ DATA
    char line[200];
    int firstTime=1,first;

    first=0;
    push(&stack,graph.nodes[first]);

    printf("ID %i\n",stack.anfang_->node.id);
    printf("ID %i\n",stack.anfang_->node.id); …
