每当我尝试读取文本文件时,都会遇到流问题和提取问题,并且无法在控制台输出上正确处理它,并且会产生大量垃圾。
谁能向我展示使用代码中使用的功能的正确方法?我是初学者。
#include <iostream>
using namespace std;
#include <string>
#include <cstring>
#include <fstream>
struct student {
char rollnum[28]; //struct to store data
char course[4];
int md, ss, fn;
};
int main()
{
ifstream fin("okhi.txt"); //file openning here
if (fin)
{
student dat[21];
string h1, h2; //strigs to get 1st two lines as it is
getline(fin, h1); fin.clear();
getline(fin, h2); fin.clear();
cout << h1 << endl << h2 << endl;
for (int x = 0; x < 21; x++)
{
dat[x].md = dat[x].ss = dat[x].fn = 0;
}
for (int x = 0; x < 21; x++)
{
fin.getline(dat[x].rollnum, 28);
cout << dat[x].rollnum;
fin.clear();
fin.getline(dat[x].course, 4);
cout << " " << dat[x].course;
fin.clear();
fin >> dat[x].md;
cout << " " << dat[x].md;
fin >> dat[x].ss;
cout << " " << dat[x].ss;
fin >> dat[x].fn;
cout << " " << dat[x].fn<<endl;
fin.clear();
fin.ignore();
}
cout << dat[0].rollnum << endl;
}
}
