怎样输出到文件,如输出到文本文档.(C++)

[HNLGDXYJS]

怎样输出到文件,如输出到文本文档.用C++语言.
比如,我想把"SDFGASSADFSGSDG"这些东西输出到文本文档并保存,要怎样写代码?
我知道要这个头文件(fstream)但我不知具体怎样用.麻烦大伙指点一下,谢谢了.

#include <fstream>

void main()
{
ofstream outfile("test.txt");
outfile << "hello world" << endl;
outfile.close();
}

[HelloDan]

#include<iostream>
#include<fstream>
using namespace std;


int main()
{     
	ofstream outfile("abc.txt");
	outfile<<"fdtgerqyeophy"<<endl;
	outfile.close();


	return 0;
}

用ofstream


接分来了

[五号智能]

include<iostream>
#include<fstream>

usingnamespacestd;

intmain()
{   
    string a="SDFGASSADFSGSDG" ; 
    ofstream outfile("abc.txt");
    outfile<<a<<endl;
    outfile.close();
    return0;
}

方法2

class Hotel
{
	private:
		int No;						
		string name;					
		string cty;					
		int total_room;					
		int proom;					
		int proom_empty;				
		double proom_money;				
		int hroom;					
		int hroom_empty;				
		double hroom_money;				


	public:




        // 运算符重载决定了写到文件的文本格式

	friend ostream&
	operator	<< (ostream &out,Hotel &hot)
	{
		out <<hot.No<<" "<<hot.name<<" "<<hot.cty<<" "<<hot.total_room<<" "<<hot.proom
			<<" "<<hot.proom_empty<<" "<<hot.proom_money<<" "<<hot.hroom
			<<" "<<hot.hroom_empty<<" "<<hot.hroom_money<<endl;
				
		return out;
	}

 	friend istream&
	operator >> (istream &in,Hotel &hot)
	{
		in  >> hot.No >> hot.name >> hot.cty >> hot.total_room >>hot.proom
			>> hot.proom_empty >> hot.proom_money >>hot.hroom
			>> hot.hroom_empty >> hot.hroom_money;
		return in;
	}		       
};


 int loadfile(list<Hotel> &list_hot)                            //读文件
{
	ifstream infile("hot.dat");

        while (infile >> temp)
		{
			temp.num(num);
			list_hot.push_back(temp);
			num++;
		}
	infile.close();
	infile.clear();
}

void savefile(list<Hotel> &list_hot)                      ／／写文件
{
	ofstream outfile("hot.dat");
		
		for(list<Hotel>::iterator li_hot=list_hot.begin();li_hot!=list_hot.end();li_hot++)
		{
			outfile<<*li_hot;
		}
		outfile.close();
		outfile.clear();
}
