How to extract all words from a string into a vector by multiple delimiters in C++

Answer 1

#include <iostream>
#include <vector>
#include <sstream>

int main() {
    std::string s = "c c++:java, python:php javascript = c#";
    char delimiters[] = " ,:=";
    std::vector<std::string> words;
    
    std::stringstream stringStream(s);
    std::string line;

    while (std::getline(stringStream, line)) {
        std::size_t prev = 0, pos;
        while ((pos = line.find_first_of(delimiters, prev)) != std::string::npos) {
            if (pos > prev)
                words.push_back(line.substr(prev, pos-prev));
            prev = pos + 1;
        }
        if (prev < line.length())
            words.push_back(line.substr(prev, std::string::npos));
    }

    for (const auto &str : words) 
        std::cout << str << "\n";      
}
