int args and char argv[] are used for detecting command line arguements
eg.
./a.out first_arg second_arg
here, int args detects, no. of arguements, in our case, its 3 (including ./a.out)
char argv stores the arguement
in our case,
argv[0] = a.out
argv[1] = first_arg
argv[2] = second_arg
and yes
variables can be declare outside/before main function,
they are called global variables
