/*
 * bomblab_warmup.c
 *
 * On shannon.marlboro.college :
 * 
 *   $ gcc -Og bomblab_warmup.c -o warmup
 *
 *   (The -Og option means "optimize to help debugging".)
 *
 *   $ ./warmup
 *   1: What is the magic word? ummm
 *   BOOM!
 *
 *   $ ./warmup
 *   1: What is the magic word? magick
 *   2: What is the number? 13
 *   Success.
 *
 * Your mission : use (gdb, objdump, strings, ...) to figure out what 
 * to type from the ./warmup file, not from this source file.
 *
 *   $ objdump -d warmup > warmup.objdump
 *   $ strings warmup > warmup.strings
 *
 *   $ gdb warmup
 *   ... see ./gdb_notes.txt for some ideas.
