Thread: Structure pointer help

How would I go about doing this? I have a structure pointer and inside the structure is a pointer to a char. Here is what I have sofar, but it crashes.

Code:

#include <stdio.h>

char doug[] = "Doug";

struct structure
{
	char* name;
}*struct_ptr;

int main()
{
    struct_ptr->name = &doug[0]; // This causes the freezing
    printf("&#37;s",*struct_ptr->name);
    return 0;
}

I know that the problem is the assigning of the address of the string to the structure, but I don't know how to fix that. Thanks in advance.

I searched and searched google, this site, and other references, but I haven't come across how to assign the address of a char to a member exactly like the above example.

The line you think is causing the issue isn't the real problem. Lose the '*' char in the printf() statement.

Nice name, and welcome to cboard.

struct_ptr isn't pointing to anything.

Code:

struct s
{ int a; };

int main()
{
    struct s my_s;
    struct s *sp;
    sp = &my_s;

    (*sp).a; // is the same thing as
    sp->a;
    return 0;
}

Code:

#include <stdio.h>

char doug[] = "Doug";

struct structure
{
    char* name;
}*struct_ptr;

int main()
{
    struct_ptr->name = &doug[0]; // struct_ptr is not pointing to anything in particular.
    printf("&#37;s",*struct_ptr->name); // use "printf("%s", struct_ptr->name);". -> already dereferences struct_ptr.
    return 0;
}

Code:

#include <stdio.h>

char doug[] = "Doug";

struct structure
{
    char* name;
} *struct_ptr;

int main()
{
    struct structure sinstance; // something for struct_ptr to point to
    struct_ptr = &sinstance;
    struct_ptr->name = doug; // doug means the same thing as &doug[0]. sinstance.name now equals "Doug".
    printf("%s",struct_ptr->name);
    return 0;
}

Unbelievable, I can't believe I missed that.

/me goes to cry in the corner.
