有一个项目,我应该要求用户输入文件名,然后获取该文件并制作一个结构数组。我完全迷路了!这是我到目前为止所拥有的
#include <iostream>
#include <fstream>
#include <string>
#include <iomanip>
using namespace std;
string filename;
ifstream inFile;
struct ftballPlayer
{
int NO;
string first;
string last;
char POS;
char clas;
int height;
char ds;
int iheight;
string hometown;
};
int counter=0;
const int MAX_PLAYER=50;
void printList(const ftballPlayer list[], int listSize);
void printOne ( ftballPlayer two);
void getData(ifstream& inFile, ftballPlayer list[], int& listSize);
int main ()
{
ftballPlayer list[MAX_PLAYER] ;
cout << "Enter the name of the input file: " ;
cin >> filename;
inFile.open(filename.c_str () );
if (!inFile)
{
cout<<"Cannot Open Input File."<<endl;
cout<< "Program Terminates!"<<endl;
return 1;
}
inFile.ignore (200,'\n');
getData (inFile, list, counter);
for ( counter = 0;counter < 50;counter++)
{
printOne (list[ counter] ) ;
cout <<endl;
}
return 0;
}
void getData(ifstream& inFile, ftballPlayer list[], int& listSize)
{
ftballPlayer item ;
listSize = 0;
inFile >> item.NO >> item.first >> item.last
>> item.POS >> item.clas >> item.height
>> item.ds >> item.iheight >> item.hometown;
while (inFile )
{
list [listSize ] = item ;
listSize++;
inFile >> item.NO >> item.first >> item.last
>> item.POS >> item.clas >> item.height
>> item.ds >> item.iheight >> item.hometown;
}
inFile.close () ;
}
void printList(const ftballPlayer list[], int listSize)
{
int looper;
for ( looper = 0; looper < listSize ; looper++)
{
printOne ( list [looper] );
cout << endl ;
}
}
void printOne ( ftballPlayer one)
{
cout << fixed << showpoint << setprecision (2);
cout << "NO " << one.NO;
cout << setw(5) << left << " Name: " << one.first << " " << one.last;
cout << " POS " << one.POS << setw(5);
cout << "Class "<<one.clas<<setw (5);
cout << "Height "<<one.height<<" "<<one.ds<<" "<<one.iheight<<setw(5);
cout << "Hometown " << one.hometown << endl;
}
有人能告诉我我是否走在正确的轨道上吗?我得到的打印输出甚至不接近文本文件。

这是用户可以输入的三个之一,但它们都具有相同类型的信息。我查看了我的教科书,并且已经在网上搜索了几个小时,当用户输入文件而不是从文件开始时,我找不到任何关于这样做的信息。任何帮助或方向将不胜感激。
