DESCRIPTION
If you wish to retrieve the arguments passed to your application via the command line through the
top
If you wish to retrieve the arguments passed to your application via the command line through the

ERRORS
It is undefined behaviour if
top
It is undefined behaviour if
argc is less than the actual number of elements in the argument array.
top
CONSIDERATIONS
Care needs to be taken with argument handling as neither this function nor any functions in the
top
Care needs to be taken with argument handling as neither this function nor any functions in the
argparser class do any argument validation (i.e. user input validation).
