Everyone a great god is good, I want to achieve a function calls to the vector container, rather than a pointer, the main function, called the vector, CPP, call the function is a sum function, a function called atsum. CPP, function header files for atsum. H,
The following is the main program

 
#include 
#include 
# include "ATSUM. H" 
using namespace std; 

Int main () 
{
Const int N=100; 
Vector A (N); 
Double s=0; 
ATSUM Sum; 
Sum. Atsum (a, s); 
Coutreturn 0; 
} 

ATSUM. H header file content is

 
# # ifndef CLASSSUM_H 
# define CLASSSUM_H 
#include 

The class ATSUM 
{
Public: 
Void atsum (STD: : vector & A, double s); 
}; 

# endif 

Function atsum. CPP for

 
#include 
#include 
# include "ATSUM. H" 

using namespace std; 

Void ATSUM: : ATSUM (vector & A, double s) 
{
for(int i=0; i!=a.s considering (); I++) 
S=s + a, [I]. 
} 

Compile after error for

 
/TMP/ccC8QCeF. O: : in the function 'main' 
Vector. CPP: (. Text + 0 xe7) : 
'ATSUM: : ATSUM (STD: : vector & , double) 
 'Undefined reference 

The STD: : vector In the source program for STD: : vector & Right, this come from? And how to make the call? Please god,

Procedures should be no problem,
The compiler code of what there is a problem,
