C++击球平均值程序使用输入/输出文件打印名称，平均值，最高/最低平均值时遇到麻烦

我有这个击球平均程序。我的问题是我无法使用输入/输出文件输出此程序，以便它显示最高/最低平均值以及与之相关的名称。我在main中的代码不正确，因为它只输出"最高击球平均值是：0"和"平均击球率最高的球员："没有一个平均值是0，所以它不应该输出它，并且在最高击球平均值旁边应该有一个名字。最低的也是如此。这是我到目前为止所拥有的：

#include "Player.h"
#include "Stack.h"
#include <fstream>
using namespace std;
int main()
{
Player x;
string name;
double avg;
ifstream infile("avgs.txt"); 
while (infile >> name >> avg)
{
x.insertPlayer(name, avg);
}
infile.close();
x.printHigh();
x.printLow();
if(!infile)
{
cout << "Unable to open the file for writing " << endl;
exit(0);
}
ofstream outfile("avgs.txt");
if (!outfile)
{
cout << "Error opening file " << endl;
exit(0);
}
outfile << endl;
}

以下是 Player 类和 Stack 类的文件，以防需要：

////Player.h
#include "stdafx.h"
#include <iostream>
#include <string>
#include "Stack.h"
using std::string;
class Player
{
public:
double lowest;
double highest;
Stack<string> low;
Stack <string> high;
void insertPlayer(string name, double batAvg);
void printHigh();
void printLow();
};

这是 Player 类的.cpp文件：

#include "stdafx.h"
#include <iostream>
#include <string>
#include "Player.h"
using namespace std;
using std::string;
void Player::insertPlayer(string name, double batAvg)
{
cout << "Player " << name << " has an average of: " << batAvg << endl;
if (low.empty() && high.empty())
{
low.push(name);
high.push(name);
highest = lowest = batAvg;
}
else
{
if (batAvg>highest)
{
while (!high.empty())
high.pop();
highest = batAvg;
high.push(name);
}
else if (batAvg == highest)
high.push(name);
else if (batAvg<lowest)
{
while (!low.empty())
low.pop();
lowest = batAvg;
low.push(name);
}
else if (batAvg == lowest)
low.push(name);
}
}
void Player::printHigh()
{
cout << "Highest batting average is: " << highest << endl;
cout << "Players with the highest batting average: " << endl;
}
void Player::printLow()
{
cout << "Lowest batting average is: " << lowest << endl;
cout << "Players with the lowest batting average: " << endl;
}

如果需要，还有我的 Stack 类：

#ifndef STACK
#define STACK
#include "stdafx.h"
#include <iostream>
#include <vector>
using namespace std;
template <class T>
class Stack : public exception
{
private:
vector<T>myStacks;
public:
void push(T const& uStack);
void pop();
T peek() const;
bool empty() const
{
return myStacks.empty();
}
};
template <class T>
void Stack<T>::push(T const& uStack)
{
myStacks.push_back(uStack);
}
template <class T>
void Stack<T>::pop()
{
if (myStacks.empty())
{
throw std::out_of_range("Stack <>::pop(): This is an empty stack ");
}
myStacks.pop_back();
}
template <class T>
T Stack<T>::peek() const
{
if (myStacks.empty())
{
throw std::out_of_range("Stack<>::peek(): This is an empty stack ");
}
return myStacks.back();
}
#endif

我尝试输出的焦点代码是 Player.cpp，但需要 Stack.h 和 Player.h 才能使其运行。在main((中，我需要输出名称，平均值和具有最高/最低平均值的人。任何帮助不胜感激！

文本文件由球员及其平均值组成，例如： 奥兰多.775 查尔斯.606 法学博士 .775 吉娜.400 山姆.702 丰富 .686

等等。
