I am trying to use scanf() to read in input someone types to the command line after the program is running. The problem i am running into is i need multiple different forms of input. For example they might type "quit" the first time and "quit 5" the next. Is there a way to pull the entire thing in as a string and then parse out the quit and the number if it got entered? I want to be able to have a char[] with quit inside and the 5 stored as an int. Thanks for your help.
use fgets and sscanf pair

methinks the scanset functionality of scanf() is your best bet
Code:char s[100]; scanf("%[^\n]", s);
What vart suggested might be better, especially since your example is a bad bet. It should be:Originally Posted by itCbitC
Code:char s[100] = ""; scanf("%99[^\n]", s);

Well fgets() and sscanf() would work just as well as [s]scanf() with the scanset control string format.
And yes to prevent going out-of-bounds it's a good idea to prefix the length of the target array in the control string.

Just that scanf is a lot more complex itself... You do not use space shuttle to get to the shop next door?
