使用新行分隔符遍历文件的最佳方法

with open('file.txt', 'r') as file:
    lines = file.readlines()
    for line in lines:
        line = line.rstrip('\n')
        # 处理每一行的数据

try (BufferedReader br = new BufferedReader(new FileReader("file.txt"))) {
    String line;
    while ((line = br.readLine()) != null) {
        // 处理每一行的数据
    }
} catch (IOException e) {
    e.printStackTrace();
}

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

int main() {
    std::ifstream file("file.txt");
    std::string line;
    while (std::getline(file, line)) {
        // 处理每一行的数据
    }
    file.close();
    return 0;
}
