v2:
Split v1 up to separate commits for each logically independent change

Dehan Meng (4):
  sscanf return values are checked to ensure correct parsing.
  Proper initialization of n to 0 for getline to function correctly.
  Avoiding freeing line prematurely. It's now only freed at the end of
    the function.
  For correcting code style: Variable declarations moved to the
    beginning of blocks Followed the coding style of using snake_case
    for variable names. And merged redundant route and networkroute
    variables.
