In C Code:

Consider the following long option declaration: struct option longOptions{} { {"userName",1 ,0, 'u'}, { "active", 0, 0, 'a'},

{ "level", 2, 0, 'L'}, //value from 0.0 to 5.0

{ "rating", 1, 0, 'R'}, //value from 100 to 1000

{ 0,0,0,0}

};

1) Create a short option string based on the above. 2) Write a getopt loop to capture all 4 flags.
