如何在C ++中读取受两个单词限制的.txt文件中的内容

#include <fstream>
#include <iostream>

int main() {
    std::ifstream file("file.txt");
    if (!file) {
        std::cerr << "Failed to open file." << std::endl;
        return 1;
    }
    
    // 读取文件内容的代码将放在这里
    
    file.close();
    return 0;
}

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

int main() {
    std::ifstream file("file.txt");
    if (!file) {
        std::cerr << "Failed to open file." << std::endl;
        return 1;
    }
    
    std::string word;
    int wordCount = 0;
    while (file >> word) {
        // 处理每个单词的代码将放在这里
        
        wordCount++;
        if (wordCount >= 2) {
            break;  // 达到限制的单词数，退出循环
        }
    }
    
    file.close();
    return 0;
}
