C++实现读取文件，输出单词

#include <iostream> 

#include <fstream> 

#include <string> 

using namespace std; 



int main() 

{ 

	const char filename[]="f:\\text.txt"; 

    ofstream o_file;

    ifstream i_file;

    string out_text; 



	//写 

    o_file.open(filename); 

    for(int i =0;i<=12;i++) 

	{ 

		o_file<< "a" << i <<' ';//将内容写入文本 

	} 

    o_file.close(); 



	//读 

    i_file.open(filename); 

    if(i_file.is_open()) 

	{ 

		while(i_file>>out_text)  

			cout << out_text << endl; 

	} 

	else 

		cout<<"打开文件:"<<filename<<"时出错!"; 



	i_file.close();

	return 0; 

}
