i need help writing a program that involves graph traversal... how do i read in the graph from a file whose name is specified on the command-line?
Also, how can i do the following?
1.) Ask the user what node to start at, and whether to perform breadth-first or depth-first traversal
2.) Put the graph-specific code into a library of graph-related functions (ie, like the Stack and Queue libraries).
thanks!
What have you come up with so far?

Declare a pointer to FILE, then use fopen to open the file. Reading can be done by for example fgetc or fread.

You could use scanf to get the option from the user.

Use fputc, fwrite, something like that.
