Thread: namespace std is showing as nonexistent

on my VC5.0. Why must this be? Is VC5.0 not good for win2k?


//DrinkOfTheDay.cpp

#include "DrinkOfTheDay.h"
#include <fstream.h>
using namespace std;//E:\MyITProjects\CandCPP\DrinkOfTheDay\DrinkOfTheDa y.cpp//(14) : error C2653: 'std' : is not a class or namespace name


DrinkOfTheDay:rinkOfTheDay()
{
Drink=new Monday;
}
DrinkOfTheDay:rinkOfTheDay(Monday* Drink)
{
// read from file named data.dat
ifstream from ("data.dat");
if (!from) error("cannot open input file*, "data.dat");


}
void error(const char* p, const char* p2 = "")
{
cerr << p << ' ' << p2 << '\n";
exit(1);
}

<cstdio>

namespace std {
#include <stdio.h>
};

Include the standard header <cstdio> to effectively include the standard header <stdio.h> within the std namespace.

guess the cstdio is only for <stdio.h> within the std namespace.

Thanks
