How to tokenize a std::string using strtok?

Tokenizing a std::string with strtok

Tokenizing a std::string using strtok requires converting it into a char for compatibility. However, trying to use str.c_str() results in a const char type, which is not suitable for strtok.

One solution is to use an istringstream object, which allows you to treat a string as a sequence of tokens. Here's an example:

#include <iostream>
#include <string>
#include <sstream>

int main() {
    std::string myText("some-text-to-tokenize");
    std::istringstream iss(myText);
    std::string token;

    // Use getline() to extract tokens separated by '-'
    while (std::getline(iss, token, '-')) {
        std::cout << token << std::endl;
    }

    return 0;
}

Alternatively, consider using the Boost C Libraries, which provide additional string manipulation and tokenization functions, offering more flexibility and control.
