C problem struct and string


Posted on 16th Feb 2014 07:03 pm by admin

Hi guys,

This is my first post and I'm hoping the experts here can help me solve my problem.

- I'm trying to create a linked list in C and the codes look like this:

#include "stdio.h"
#include
#include
using namespace std;

struct dir_list
{
int level;
string dir_name;
struct dir_list * head;
struct dir_list * tail;
};

typedef struct dir_list * dir;

void main()
{
dir curr;

curr=(dir)malloc(sizeof(string)+sizeof(dir));
curr->level=0;
curr->dir_name="test ";
curr->head=NULL;
curr->tail=NULL;
}

The problem with this code happens at the string assignment curr->dir_name="test "; and the executable will stop responding once run. I suspect the problem could be caused by the size of malloc but the result stays the same after I increased that number.

Can anyone explain to me what the problem is?

Greatly appreciated!
