我有一段代码不会编译。C++排序二进制文件
#include "stdafx.h"
#include <iostream>
#include <fstream>
#include <string>
#include <Windows.h>
#include <iomanip>
using namespace std;
int average (int n);
int main()
{
string filename;
int i,j;
int n = 0;
int sum = 0;
int size = 4;
const int nameLength = 19;
const int maxRecords = 100;
int index[100];
int scores[maxRecords];
char names[maxRecords][nameLength];
int count = 0;
cout << "Enter binary data directory and file name: ";
getline (cin, filename);
// Open file for binary read-write access.
ifstream fin(filename.c_str(), ios::binary);
if (!fin) {
cout << "Could not open " << filename << endl;
system("PAUSE");
return -1;
}
// Read data from the file.
while (
fin.read(names[count], sizeof(names[0]))
&& fin.read((char *) &scores[count], sizeof(scores[0]))
)
{
count++;
fin.ignore(); // skip the padding byte
}
// Display the data and close.
cout << "Your file's data unsorted: " << endl;
cout << endl;
cout << setw(10) << "Name" << setw(20) << "Test Score" << endl;
for (i=0;i<n;i++){
cout << setw(10) << names[i] << setw(20) << scores[i] << endl;
}
for (i=0;i<n;i++)
{
index[i]=i;
}
for (i=0;i<n;i++)
{
for (j=i+1;j<n;j++)
{
int temp;
if (scores[index[i]] > scores[index[j]])
{
temp = index[i];
index[i] = index[j];
index[j] = temp;
}
}
}
cout << "The average of the test scores in your file is: " << average (sum);
sum=sum+scores[i];
fin.close();
system("PAUSE");
return 0;
}
int average (int sum, int size)
{
return sum/size;
}
我收到说编译错误:fatal error LNK1120: 1 unresolved externals
,我想不通为什么。另一个问题是如何格式化它,以便从原始二进制文件中读取的数据不会被篡改,然后输出并保存在新的编辑后的二进制文件中?
什么是确切的错误信息? –
为什么“”包含在内,但不包含“”?我在这里没有看到前者的任何内容,但'system'来自后者,而不是'system(“PAUSE”)'代码应该有的东西。 –

错误消息说,“”致命错误LNK1120:1个未解决的外部事件“”,并且我早先在那里有因为我在那里有一个MAX_PATH事物,我拿出来了。 –
