为什么C++的文件I/O在读取文本文件时忽略了开头的空行?我怎么才能让它不这样做呢？

#include <iostream>
#include <fstream>

int main() {
    std::ifstream file("example.txt");
    file >> std::noskipws;

    char c;
    while (file >> c) {
        std::cout << c;
    }

    file.close();
    return 0;
}

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

int main() {
    std::ifstream file("example.txt");
    std::string line;

    while (std::getline(file, line)) {
        std::cout << line << std::endl;
    }

    file.close();
    return 0;
}
