What is wrong with the program?

#include <iostream>                                                   //Line 1

namespace mySpace                                                   //Line 2

const double RATE = 15.35;                                      //Line 4
int a;                                                                            //Line 5

cout << RATE << " " << a + 2 << " " << b    //Line 12
<< endl;                                                           //Line 13

Return 0;                                                         //Line 14
}   //Li
