how do you declare code?

Code:

---

#include <iostream>
int main()
{
 int age;
 char string[256];
 cout<<"Please enter your name and birthdate: ";
 cin>>string>>age;
 cout<<"Welcome"<<string<<","<<age<<endl;
 system ("pause");
 return 0;
}

I get several error of my cout and cin ( and endl) commands being undeclared, but how do you declare something?

using namespace std; is your friend

or use the older header, iostream.h

Code:

---

#include <iostream>
using namespace std;

int main()
{
 int age;
 char string[256];
 cout<<"Please enter your name and birthdate: ";
 cin>>string>>age;
 cout<<"Welcome"<<string<<","<<age<<endl;
 system ("pause");
 return 0;
}

could you also give me a list of the different streams like iostream and that stuff and what their functions are?

i rmemeber a link on here about exactly what your asking, but cant remember it exactyl...looking around now.

edit: this is kinda what your looking for, but not the one im thinking of.

"could you also give me a list of the different streams like iostream and that stuff and what their functions are?"

cin--input from your keyboard.
cout--output to your display.

Both are defined in <iostream>.

fstream is for files
istringstream is for input stringstreams
ostringstream is for output stringstreams
