使用C++拆分单词

#include <iostream>
#include <string>
#include <vector>

std::vector<std::string> splitWords(const std::string& text) {
    std::vector<std::string> words;
    std::string word;
    for (char c : text) {
        if (c == ' ' || c == '\t' || c == '\n') {
            if (!word.empty()) {
                words.push_back(word);
                word.clear();
            }
        } else {
            word += c;
        }
    }
    if (!word.empty()) {
        words.push_back(word);
    }
    return words;
}

int main() {
    std::string text = "Hello, world! This is a sample text.";
    std::vector<std::string> words = splitWords(text);
    for (const std::string& word : words) {
        std::cout << word << std::endl;
    }
    return 0;
}
