C ++如何读取带逗号

Question

我有一个198的文件（但它可以在0-200之间）。我文件的每一行都是这样的：

Urdnot Wrex,2.75,198846.13
Urdnot Bakara,3,189484.84
Hannah Shepard,1.75,188145.14
David Anderson,2.25,182169.46
Kasumi Goto,2.75,176795.83

这是我的代码，但是，它不想工作。

int index = 0; // The index of the file.

while(index <= 200) {
    in.ignore(256, ',');
    in >> employeeName;
    in.ignore(256, ',');
    in >> employeeScore;
    in.ignore(256, '\n');
    in >> employeeSalary;

    cout << index << ": " << employeeName << ", " << employeeScore << ", " << employeeSalary << endl;
    index++;
}

但是，对于198行的文件，它只读取3，输出为：

0: 2.75,198846.13, 3, 0
1: 2.75,198846.13, 3, 0
2: 2.75,198846.13, 3

如果有人对如何使其发挥任何想法，那将非常感激。

像这样：

#include <fstream>

std::ifstream infile("thefile.txt");
if (infile.is_open()) {
    float number;
    std::string str;
    char c;
    while (infile >> str >> >> c >> number && c == ',')
        cout << number << " " << str << "\n";
}
infile.close();
