你如何从C++文件中读取一个单词？

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

int main() {
    std::ifstream inputFile("input.txt");
    std::string word;

    if (inputFile >> word) {
        std::cout << "读取的单词是: "<< word<< std::endl;
    } else {
        std::cout << "无法读取单词"<< std::endl;
    }

    inputFile.close();
    return 0;
}
