#include <iostream>
#include <string>
#include <cctype>

int main() {
    std::string str = "Hello, World!!!";
    std::string punctuation = "!\"#$%&'()*+,-./:;<=>?@[\\]^_`{|}~";

    // 替换标点符号为空格
    for (auto& c : str) {
        if (std::ispunct(c)) {
            c = ' ';
        }
    }

    std::cout << str << std::endl;

    return 0;
