Lecture Notes: 05 Arrays

Longest Word

#

• Plan:
  • Read /usr/share/dict/words into an array.
  • Make an array of lengths.
  • index of longest
  • We’ll use malloc for everything
• Makefile first.
  • gcc command
  • clean rule
  • tabs
• Get distracted by:
  • Standard library functions and headers:
    • stdio.h: printf, fscanf, fgets
    • stdlib.h: atol
    • math.h: ceil, sqrt – show manpage, talk about libm
  • Casts. For numbers, these convert.
