这个文件   有错：
#include   "sales.h "
#include   <iostream>

using   namespace   std;
namespace   SALES
{

Sales::SetSales()
{
sales[QUARTERS]   =   {0,   0,   0,   0};
average   =   0;
max   =   0;
min   =   0;
}

void   Sales::SetSales(Sales   &s)
{
int   count   =   0;
double   sale;

cout   < <   "Enter   the   sale:   ";

while   (cin   > >   sale   &&   count   <   4)
{
s.sales[count]   =   sale;
count++;
cout   < <   "Enter   the   next   sale:   ";
}

double   total   =   0;
s.max   =   s.sales[0];
s.min   =   s.sales[0];

for   (int   index   =   0;   index   <   count;   ++index)
{
total   +=   s.sales[index];

if   (s.max   <   s.sales[index])
s.max   =   s.sales[index];
if   (s.min   >   s.sales[index])
s.min   =   s.sales[index];
}

s.average   =   total/count;
*this   =   s;
}

void   Sales::ShowSales()   const
{
cout   < <   "The   Sales   informations   is...\n ";

for   (int   index   =   0;   index   <   QUARTERS;   index++)
{
cout   < <   "The   sale   "   < <   index   < <   "   is:   "   < <   sales[index]   < <   endl;
}

cout   < <   "The   Average   is:   "   < <   average   < <   endl
< <   "The   Max   is   :   "   < <   max   < <   endl
< <   "The   Min   is   :   "   < <   min   < <   endl;
}
};
提示是：
d:\c++习题\primer   plus\第十章\4\sales.cpp(10)   :   error   C2059:   syntax   error   :   '{ '

sales.obj   -   3   error(s),   0   warning(s)

这什么情况？弄的人很是郁闷。
地下是头文件：
#ifndef   SALES_H_
#define   SALES_H_

namespace   SALES
{
const   int   QUARTERS   =   4;
class   Sales   {
private:
double   sales[QUARTERS];
double   average;
double   max;
double   min;
public:
SetSales();
void   SetSales(Sales   &s);
void   ShowSales()   const;
};
};

#endif

主函数就不写了没什么意义！
