C ++以2D数组读取文件

Question

I'm almost frustrated with this program. I have a file that contains 100 records but, my output will not go beyond 17 including the header. Can anyone tell me what I am doing wrong?

#include "stdafx.h"
#include <iostream>
#include <fstream>

using namespace std;

char medRecord[100][8];
int header, person;

int main()
{

    ifstream in("fakedata.txt");
    if(!in){
        cout << "Cannot open file. \n";
        return 1;
    }

in.read((char *) &medRecord, sizeof medRecord);

for(person = 0; person < 100; person++)
     for(header = 0; header < 8; header++)
cout << medRecord[person][header] << "";

return 0;

}

Output:

Answer 1

Your medRecord array contains 800 characters. The outputted text contains 783 characters, one line short (or less) of 800. So, sight unseen, what you're probably doing is trying to read the entire file into medRecord , and the readin or outputting stops when it gets filled up.

I counted by cutting/pasting into Open Office--if the newlines aren't getting counted properly, then 783 + 17 = 800 and there you go.
