Answer 1

#include <iostream>
#include <string>

int main() {
    std::string s = "c  c++  \n    c#  \r java  \t  python";
    std::string delimiters = " \n\r\t";
    std::string token;
    std::size_t pos;

    while ((pos = s.find_first_of(delimiters)) != std::string::npos) {
        token = s.substr(0, pos);
        if (token != "") {
            std::cout << token << std::endl;
        }
        s.erase(0, pos + 1);
    }

    if (!s.empty()) {
        std::cout << s << std::endl;
    }
}
