   - ```-a``` and ```-b``` become true.
   - argv is further parsed to identify the inputs mapped to ```-c```.
 * Using ```-cab``` will throw an error since argparse expects two inputs for the argument ```-c```.

-Both of these above statements will work. Argparse has specializations implemented for both ```std::vector``` and ```std::list```.
