Answer 1

使用字符串流将字符串拆分为单词:

#include <sstream>

bool is_similar(string str1, string str2)
{
    vector<string> words1, words2;
    string temp;

    // Convert the first string to a list of words
    std::stringstream stringstream1(str1);
    while (stringstream1 >> temp)
        words1.push_back(temp);

    // Convert the second string to a list of words
    std::stringstream stringstream2(str2);
    while (stringstream2 >> temp)
        words2.push_back(temp);

    int num_of_identical_words = 0;
    // Now, use the code you already have to count identical words
    ...

    double ratio = (double)num_of_identical_words / words2.size();
    return ratio > 0.6;
}
