请大家帮忙找一个错误，错误的原因在哪里？

该程序完成字符串统计，然后输出：

#include<iostream>
#include<map>
//#include<utility>
#include<fstream>
//#include<string>

using namespace std;

int main(void)
{
map<string, int> word_count;
string word;
map<string, int>::iterator num;

ifstream f(".\\54.txt", ios::in | iso::nocreate);

if (!f) //open file fail
{
cerr << "54.txt file not open!" << endl;

exit(1);
}

while (f >> word)
{
//insert element with key equal to word and value 1;
//if word already in word_count, insert does nothing;

pair<map<string, int>::iterator,bool> ret = word_count.insert(make_pair(word, 1));

if (!ret.second)
{
++(ret.first->second);
}

}

num = word_count.begin();

while (num != word_count.end())
{
cout << num->first;
cout << " : " << num->second << endl;

num++;
}


f.close;

return 0;

}

//编译错误：
error:statement cannot resolve address of over loaded function

}

别的我不知道，这个
ifstream f(".\\54.txt", ios::in | iso::nocreate); 是不是有点问题,实在linux么？那怎么会有\\

GCC 4.4.1通过！

#include <iostream>
#include <map>
//#include <utility>
#include <fstream>
#include <string>
#include <stdio.h>
#include <stdlib.h>

using namespace std;

int main(void)
{
    map <string, int> word_count;
    string word;
    map <string, int>::iterator num;

    ifstream f(".\\54.txt", ios::in | ios::trunc);

    if (!f) //open file fail
    {
        cerr << "54.txt file not open!" << endl;

        exit(1);
    }

    while (f >> word)
    {
//insert element with key equal to word and value 1;
//if word already in word_count, insert does nothing;

        pair <map <string, int>::iterator, bool> ret = word_count.insert(make_pair(word, 1));

        if (!ret.second)
        {
            ++(ret.first->second);
        }

    }

    num = word_count.begin();

    while (num != word_count.end())
    {
        cout << num->first;
        cout << " : " << num->second << endl;

        num++;
    }


    f.close();

    return 0;

}

是在linux下编译

[goodname]

都已经给你了正确的代码了，自己仔细看看。

大概有三处错误
第一应该
#include <string>


2
ios::in | ios::trunc

3

f.close();

[jkx01whg]

是在linux下编译的*.cpp文件
