输入两位小数的英语单词，转化为两位小数。C++

你可以使用 C++ 标准库中的 `std::stringstream` 类来实现这个功能。以下是一个示例代码：

#include <iostream>
#include <string>
#include <sstream>

int main() {
    std::string word = "three point fourteen";
    double number = 0.0;
    std::stringstream ss(word);
    std::string current_word;

    while (ss >> current_word) {
        if (current_word == "zero") {
            number += 0.0;
        } else if (current_word == "one") {
            number += 1.0;
        } else if (current_word == "two") {
            number += 2.0;
        } else if (current_word == "three") {
            number += 3.0;
        } else if (current_word == "four") {
            number += 4.0;
        } else if (current_word == "five") {
            number += 5.0;
        } else if (current_word == "six") {
            number += 6.0;
        } else if (current_word == "seven") {
            number += 7.0;
        } else if (current_word == "eight") {
            number += 8.0;
        } else if (current_word == "nine") {
            number += 9.0;
        } else if (current_word == "ten") {
            number += 10.0;
        } else if (current_word == "eleven") {
            number += 11.0;
        } else if (current_word == "twelve") {
            number += 12.0;
        } else if (current_word == "thirteen") {
            number += 13.0;
        } else if (current_word == "fourteen") {
            number += 14.0;
        } else if (current_word == "fifteen") {
            number += 15.0;
        } else if (current_word == "sixteen") {
            number += 16.0;
        } else if (current_word == "seventeen") {
            number += 17.0;
        } else if (current_word == "eighteen") {
            number += 18.0;
        } else if (current_word == "nineteen") {
            number += 19.0;
        } else if (current_word == "twenty") {
            number += 20.0;
        } else if (current_word == "thirty") {
            number += 30.0;
        } else if (current_word == "forty") {
            number += 40.0;
        } else if (current_word == "fifty") {
            number += 50.0;
        } else if (current_word == "sixty") {
            number += 60.0;
        } else if (current_word == "seventy") {
            number += 70.0;
        } else if (current_word == "eighty") {
            number += 80.0;
        } else if (current_word == "ninety") {
            number += 90.0;
        } else if (current_word == "hundred") {
            number *= 100.0;
        } else if (current_word == "thousand") {
            number *= 1000.0;
        } else if (current_word == "million") {
            number *= 1000000.0;
        }
    }

    std::cout << std::fixed << std::setprecision(2) << number << std::endl;

    return 0;
}

在这个示例代码中，我们使用 `std::stringstream` 类来将输入的字符串 `word` 分解成一个个单词，然后判断每个单词对应的数字大小，并进行累加。最后使用 `std::fixed` 和 `std::setprecision` 来保留两位小数输出结果。
