Alternative is basic getopt which is less powerful:

#include <getopt.h>
#include <iostream>

int main(int argc, char* argv[]) {
    option longopts[] = {
        {"prefix", optional_argument, nullptr, 'p'}, 
        {"binary", optional_argument, nullptr, 'b'}, 
        {"hex", optional_argument, nullptr, 'h'}, {0}
    };

    while (1) {
        const int opt = getopt_long(argc, argv, "pbh::", longopts, 0);

        if (opt == -1) {
            break;
        }

        switch (opt) {
            case 'p':
                // ...
                std::cout << "Remove prefix" << std::endl;
                break;
            case 'b':
                std::cout << "Binary" << std::endl;
                // ...
                break;
            case 'h':
                std::cout << "Hex" << std::endl;
                // ...
                break;
        }
    }

    //...
}
