读入一个 excel 文件到 struct c++

Question

我想将 excel 文件读入 structure.But 问题是它读取整个 excel 列 line.I 需要第一列中的数据one.Using fstreams 我打开了一个包含许多列的文件

我尝试了它 have.But 它显示了整个列的所有详细信息，如下所示

Name :      Name,Nick
Nick :   name,Phone
Phone :  number,Carrier,Address
Carrier :   Yashodhara,Yash,711256677,Mobitel,"No.
Address : 29,Bollatha,Ganemulla"
-----------------------
Name :      Madushani,Madu,711345678,Mobitel,"No.
Nick :   12,
Phone :  Gampaha"
Carrier :   Sadeepa,Sad,789002264,Hutch,"No.
Address : 123,
-----------------------

我用下面的代码试过了。

#include <iostream>
#include <string>
#include <iomanip>
#include <fstream>

using namespace std;

//structure for store contact details
struct contacts {
    string name;
    string nickName;
    string phoneNumber;
    string carrier;
    string address;
};




int main() {
    
    const int LIMIT = 10;
    contacts limit[LIMIT];
    ifstream file;
    file.open("Contact.csv");

    if (file) {
        while (!(file.eof())) {
            for (int i = 0; i <= 7; i++) {
                file >> limit[i].name;
                file >> limit[i].nickName;
                file >> limit[i].phoneNumber;
                file >> limit[i].carrier;
                file >> limit[i].address;
                
            }
        }
    }
    else {
        cout << "Error";
    }

    // Using the following to debug output
    for (int i = 0; i < 7; i++) {
        cout << "Name :      " << limit[i].name << endl
            << "Nick :   " << limit[i].nickName << endl
            << "Phone :  " << limit[i].phoneNumber << endl
            << "Carrier :   " << limit[i].carrier << endl
            << "Address : "  << limit[i].address << endl
            << "-----------------------" << endl;
    }


    return 0;
}

我想知道如何以正确的顺序将上述详细信息阅读到结构中。

您可以使用std::getline()

string readString;
if (file) {

    while (!(file.eof())) {
        getline(file,readString); // Read the column headers
        for (int i = 0; i <= 7; i++) {
            getline(file,limit[i].name,','); // ',' is the separator
            getline(file,limit[i].nickName,',');
            getline(file,limit[i].phoneNumber,',');
            getline(file,limit[i].carrier,',');
            getline(file,limit[i].address); // Read until the end of the line
            
        }
    }
}

我不得不说我没有测试它，所以它可能需要一些安排。
