member selection operator program

[rajhansk]

Why this program is not working??

  #include <iostream>
#include<cstring>
using namespace std;
struct Employee{
  char first_name[16];

};
int main()
{   struct Employee *p_emp;
    struct Employee emp;

    strcpy(p_emp->first_name,"Kumar");
    cout<<emp.first_name;

    return 0;
}

Compiler says:

 In function 'int main()':
12:37: warning: 'p_emp' is used uninitialized in this function [-Wuninitialized] 

The p_emp is a pointer. Uninitialized pointer.

The strcpy writes characters to a member of an Employee object.

Which object does the p_emp point to? Where does an uninitialized pointer point to?
Nobody knows.

I did make some changes, and it worked.
Thanks

using namespace std;
struct Employee{
  char first_name[16];

};
int main()
{   struct Employee *p_emp;
    struct Employee emp;
    p_emp=&emp;

    strcpy(p_emp->first_name,"Kumar");
    cout<<emp.first_name;

    return 0;
}
