c++ 读取文件的几种方式

//c++按行读取

/*
 * main.cc
 *

 */
#include "head.h"
using namespace std;
int main(int argc, char* argv[])
{
    printf("Starting...... \n");

    string file = argv[1];
    string tmp;
    ifstream  fin(file.c_str());
    while(getline(fin,tmp))
    {
        cout<<tmp<<endl;
    }
    printf("Ending...... \n");
    return 0;
}

//写文件

/*
 * main.cc
 *
 *  Created on: 2011-12-1

#include "head.h"
using namespace std;
int main(int argc, char* argv[])
{
    printf("Starting...... \n");
    string file = argv[1];
    string tmp;
    ofstream fin(file.c_str());
    if(fin.is_open())
    {
        fin<<"hello\n";
        fin<<"world\n";
        fin.close();
    }
    printf("Ending...... \n");
    return 0;
}

这个写的不错~  呵呵~
