How to use enum as starting args with aliases

I am trying to use enum as starting args. It should works as aliases pairs so "i" and "info" should have same value, etc...

I know it is possible to use if/else with flags, but i would like to done this using for eg. switch with int value.

#include <iostream>
#include <string>

namespace startFlags {
    enum class flag {
        i, info = 0,
        e, encrypt = 1,
        d, decrypt = 2,
        c, check = 3,
        h, help = 4
    };

    void printFlag(startFlags::flag input) {
        std::cout << "Output: " << input << std::endl; //error
    }
}

Is there any other way to deal with starting args with aliases.

You need to cast enum classes if you'd like to print them as int (or something else) even though the underlying type is int:

Example:

#include <iostream>

namespace startFlags {
    enum class flag {
        i, info = i,    // both will be 0
        e, encrypt = e, // both will be 1
        d, decrypt = d, // ...
        c, check = c,
        h, help = h
    };

    void printFlag(startFlags::flag input) {

        // Note cast below:

        std::cout << "Output: " << static_cast<int>(input) << '\n';
    }
}

int main() {
    printFlag(startFlags::flag::i);
    printFlag(startFlags::flag::info);
}
