Wednesday What do we know about recursion?  Base cases (one or more) Simplest cases Stopping points  Recursive functions call themselves  They can be hard to write  Need to make sure they stop and at each point keep breaking up the work needing to be done

Friday – Game Plan Homework 1 posted - discuss Keep working on program from last time (smallest.cpp) Computing environment

Friday Servers to run on: In Bell 216 Lab (nickelback.cse.buffalo.edu) Remote connections (timberlake.cse.buffalo.edu)

Friday To run program you need to type the name of the executable ./executableName Programs need main function. Output using cout,  Need #include to use Should put in using namespace std; to have access to all things declared in namespace called std (namespaces are like packages)

Friday Sample program (named smallest.cpp) is in directory:  ~adrienne/250/Smallest You will need to cd directly into the ~adrienne/250 directory. My ~adrienne directory is not world readable.
