要能用dev运行的代码，一段英文单词由若干单词组成，编写程序提取其中的所有单词。请实现由用户输入英文，利用字符串存储英文，提取后的单词用向量容器存储。 要编写这样

To implement a program that takes user input for an English phrase and extracts all words into a vector container in C++, you can follow these steps:

#include <iostream>
#include <sstream> // For string stream to split the input by spaces
#include <vector>   // Vector container to store words

std::string input;
std::istringstream iss; // String stream object to process the input
std::vector<std::string> words;

void extract_words() {
    std::cout << "Enter an English phrase: ";
    std::getline(std::cin, input);

    iss.str(input); // Set the string stream's string
    if (!iss.fail()) { // If there are no errors reading the input
        std::string word;
        while (iss >> word) { // Read each word from the input until end of line
            words.push_back(word);
        }
    }

    // Print the extracted words for verification
    for (const auto& w : words) {
        std::cout << w << " ";
    }
}

int main() {
    extract_words();
    return 0;
}

In this code, we use `std::getline` to get the user input as a single string, then create an `std::istringstream` to split it into individual words using `std::istringstream::operator>>(word)`. Each word is added to the `words` vector. After extraction, the program prints the words.
