一个c++ 程序编译通不过，请高手查查原因

#include <iostream>

using std::endl;

#include <iomanip>
using std::setw; // enables program to set a field width
using std::setprecision;

int main()
{
double amount; // amount on deposit at end of each year
double principal = 1000.0; // initial amount before interest
double rate = .05; // interest rate

// display headers
cout << "Year" << setw( 21 ) << "Amount on deposit" << endl;

// set floating-point number format
cout << fixed << setprecision( 2 );

// calculate amount on deposit for each of ten years
for ( int year = 1; year <= 10; year++ )

我用的是vc6.0

编译器编译时出现下边的提示：
ompiling...
fig05_06.cpp
C:\Documents and Settings\HP\桌面\c++\examples\ch05\Fig05_06\fig05_06.cpp(13) : error C2039: 'pow' : is not a member of 'std'
C:\Documents and Settings\HP\桌面\c++\examples\ch05\Fig05_06\fig05_06.cpp(13) : error C2873: 'pow' : symbol cannot be used in a using-declaration
执行 cl.exe 时出错.

fig05_06.obj - 1 error(s), 0 warning(s)

知道了，楼主用的环境一定是 VC6.0的环境。库比较旧了。
换个新环境应该不用改。

换编译器 不要因为编译器浪费了你的时间
