用C ++读取文件。 没有班级/结构/联盟

Question

I am having an error that says on line 61 that left of open must have a class/struct/union. I also have the same error on line 78. I am working in visual studio 2013. I am confused on why I need to redefine what class it is.

#include <iostream>
#include <string>
#include <fstream>
#include <cctype>

    int totalHit, totalBases;
};
struct playerUpdate
{
    string update;
    string id, firstname, lastname, division, team;
    int platApp, atBats, singles, doubles, triples, homers, sacks, walks, hitbyPitch;
    float battingAvg, onBase, Slugging;

Answer 1

You have two conflicting declarations of statsNew :

playerUpdate statsNew[1000];

ifstream statsNew;//stats 2014

Answer 2

Your statsNew is defined twice. Once as array of playerUpdate and second - as ifstream .
