G++ Error: cannot pass objects of non-POD type

[Ronin]

What does this error mean??

cannot pass objects of non-POD type

I'm using G++

POD, in C++ stands for Plain Old Data.

While u have not posted the code you have, i cannot tell your excact error, but since it says something about objects passed on and POD, i assume u are using some old data type from C, and trying to do some sort of operation that only objects in C++ can handle..

[Paradine]

Can you post your code?

[anupm]

i also got the same warning i will give u the code
#include<iostream>
#include<string>

using namespace std;

class CEmployee {
public:
CEmployee(string name = "No Name",
string id = "000-00-0000",
double salary = 0)
: _name(name), _id(id)
{
_salary = salary;
}
string getName() const {return _name;}
void setName(string name) {_name = name;}
string getid() const {return _id;}
void setid(string id) {_id = id;}
double getSalary() const {return _salary;}
void setSalary(double salary) {_salary = salary;}
void promote(double salary) const {_salary = salary;}
private:
string _name;
string _id;
mutable double _salary;
};

int
main()
{
CEmployee employee("Naren", "001-338-423", 23456) ;

fprintf(stderr, "--Name() Id(%s) Salary(%f)-------\n", employee.getid(), employee.getSalary()) ;

}

fprintf(stderr, "--Name() Id(%s) Salary(%f)-------\n", employee.getid(), employee.getSalary()) ;

Hi,

The %s argument requires a c-styled string, but you've passed it an actual std::string object.
Try:
[HIGHLIGHT="C++"]fprintf(stderr, "--Name() Id(%s) Salary(%f)-------\n", employee.getid().c_str(), employee.getSalary());[/HIGHLIGHT]
