What wrong with this code?

What wrong with this code?

#include
#include
using namespace std;

int main()
{
string a = ":)";
string b = "John";
int c = 2;
string d;
stringstream str;
str << a << " Hello " << b << " bye " << c;
d = str.str();
printf("%d",d);
getchar();
return 0;
}

d is c++ string object, and printf is C function.
Even more, not only it's C function (it would probably work nevertheless), but you've told it to print integer ( "%d" tells printf to print integer!)

Check your printf you havnt used the correct specifier

[kenji]

Check the printf your using the wrong format specifier also use the code tags.

change

printf("%d",d);

to

printf("%s", d.c_str());
