string型变量的定义问题

[angelcm51]

//程序用另一个单词代替指定单词
#include <iostream>
#include <string>
using std::cin;
using std::cout;
using std::endl;
using std::string;

int main(){
	//从键盘读取字符串
	string text;
	cout<<"please Enter a string terminated by #:  ";//terminated终止
	std::getline(cin,text,#);
	//获得要被取代的单词
	string word;
	cout<<"please Enter the word to be replaced:  ";//replaced取代
	cin>>word;
	//得到更换的单词
	string replacement;
	cout<<endl<<"Enter the replacement word:  ";
	cin>>replacement;

	if(word==replacement){
		cout<<endl
			<<"The word and it's replacement are the same."<<endl
			<<"Operation aborted."<<endl;
		exit(1);
	}
	size_t start=text.find(word);

	while(start!=string::npos){
		text.replace(start,word.length(),replacement);
		start=text.find(word,start+replacement.length());
	}
	cout<<endl
		<<"Your string is now:  "<<endl
		<<text<<endl;
	return 0;
}

为什么它说string 的定义不对呢`？说word 没有定义

LZ粗心了。

std::getline(cin,text, '#');
