Question

I want a linked list structure in my VC++ application

My structure is:-

struct xml_data {
    int id;
    char file_name[50];
    char url_source[50];
    struct xml_Data *next;
}xml_data1;

If I declare a variable like

struct xml_data *var;
const char* abc;

I want to assign a value from a const char* variable to the structure members.

I tried using

var->file_name=abc;

but it is giving an error that it cannot convert const char* to char[50]…

this may be a small problem but I am very new in using data structures….

Answer 1

After you’ve used new to allocate memory for the struct.

var = new xml_data;

Use strcpy to copy one to the other.

strcpy(var->file_name,abc);

include <cstring> and make sure there’s enough room in the destination.
