Playground error

Question

I just can't figure out why the playground doesn't run this simple code:
#include <iostream>
using name space std;
int main()
{
int *p = new int;
*p = 5;
cout <<*p<< endl;
delete p;
return 0;
}
\\ get the following errors:
"..\Playground\:2:7: error: expected nested-name-specifier before 'name'
using name space std;
^~~~
..\Playground\: In function 'int main()':
..\Playground\:8:5: error: 'cout' was not declared in this scope
cout <<*p<< endl;

namespace should be a single word
