开发一个简单错误记录功能小模块，能够记录出错的代码所在的文件名称和行号。

#include <iostream>
#include <vector>
#include <string>
using namespace std;
struct ErrordRecord //错误记录
{
public:
string pathWay;;
string fileName;
int line;
int num;//记录的数目
};

int main()
{
vector<ErrordRecord *> errordRecords;

//  while (errordRecords.size()<8)//当记录多余8条是结束程序
string pathWay;
string fileName;
int line;
while (cin >> pathWay >> line)
{

fileName = pathWay.substr(pathWay.find_last_of("\\") + 1);
bool exist = false;//如果记录是否已经存在

for (int i = 0;i < errordRecords.size();++i)
{
if (fileName == (errordRecords[i]->fileName) && line == (errordRecords[i]->line))
{
errordRecords[i]->num = (errordRecords[i]->num) + 1;
exist = true;
break;
}
}
if (exist == false)//记录不存在
{
ErrordRecord *errordRecord = new ErrordRecord();
errordRecord->fileName = fileName;
errordRecord->line = line;
errordRecord->num = 1;
errordRecords.push_back(errordRecord);
}

}

//根据数目多少输出,冒泡排序
for (int i = 0;i < errordRecords.size();++i)
{
for (int j = i + 1;j < errordRecords.size();++j)
{
if (errordRecords[i]->num < errordRecords[j]->num)
{
string fileName = errordRecords[i]->fileName;
int line = errordRecords[i]->line;
int num = errordRecords[i]->num;

errordRecords[i]->fileName = errordRecords[j]->fileName;
errordRecords[i]->line = errordRecords[j]->line;
errordRecords[i]->num = errordRecords[j]->num;

errordRecords[j]->fileName = fileName;
errordRecords[j]->line = line;
errordRecords[j]->num = num;

}
}
}

//for (int i = 0;i < errordRecords.size();++i)
for (int i = 0;i < errordRecords.size() && i < 8;++i)//输出前八条记录
{
if (errordRecords[i]->fileName.length() > 16)
{
cout << errordRecords[i]->fileName.substr(fileName.length()-16)
<< " " << errordRecords[i]->line << " " << errordRecords[i]->num << " ";
}
else {
cout << errordRecords[i]->fileName << " " << errordRecords[i]->line << " " << errordRecords[i]->num << " ";
}

}

return 0;
};
