C++程序编译为什么错?

#include "stdafx.h"
#include<limits>
#include<iostream>
#include<stdio.h>
using std::cout;
using std::endl;
using std::numeric_limits;

int main(int argc, char* argv[])

2008也没问题

[坐看昀起]

vc++ 6.0
有问题按楼主的原文件考进去的．如下
--------------------Configuration: c17_c17 - Win32 Debug--------------------
Compiling...
c17_c17.cpp
D:\c++\xiangmu17\c17_c17.cpp(30) : error C2653: 'numeric_limits<short>' : is not a class or namespace name

VC6.0加上这句

C/C++ codeusing namespace std;

我的vs05下编译也没问题

4楼,您好!我用的是VC6.0版,加上using namespace std;编译成功,谢谢您!但是我想请教您一下,为什么我用了using std::cout;
using std::endl;using std::numeric_limits; 这三个语句后还要加using namespace std;?

呵呵

你只要using namespace std;就可以了，因为这个就包含所有的std啦

你的VC是什么版本？

我的VS2005编译没问题

[baihacker]

VC9下无问题.

VC6.0加上这句

using namespace std;

VC2003也没问题
