[em03]string类的输入问题

蓝血腥人

小弟请教下一个string类怎么实现输入啊 有库函数吗？
紧急啊 大哥们

熾天使rose

利用字符数组间接输入,比如
#include "iostream.h"
#include "afx.h"
void main()
{char c[80];
CString st1;
cout<<"输入字符串:";
cin>>c;
st1=c;
cout<<"输出结果:";
cout <<st1<<endl;
}

飘香剑雨

直接就可以输入啊
#include <string>
using namespace std;
void main()
{
string str;
cin>>str;
cout<<str;
}

30岁就改变

用了楼上的程序怎么报错啊？

以下是引用lbwxqh在2006-4-29 12:28:00的发言：
直接就可以输入啊
#include <string>
#include<iostream>
using namespace std;
void main()
{
string str;
cin>>str;
cout<<str;
}

lala

可以调用函数为sting类变量赋值吗？？？
